[Zhongyingmei] The clown is actually me

Underground Wayne Manor,? Batcave.

The blue light from the bat computer illuminated the eyes of Alfred and Batman, and what appeared on the quantum display was the flat map of Gotham City.Batman sat on the chair, trying to straighten his neck so that his tired neck muscles could relax against the soft back of the chair. He clicked the button on the console, and a square log box and several A photo,? In the photo, an ambulance parked among the low bushes by the river,? Several abducted medical staff are wrapped in thermal blankets: "We have to find a reason for him to escape from prison."

"Uh, Master Bruce,? Maybe he's just bored for a long time? Just want to go out and relax." Alfred brought a cup of steaming black tea.

"Impossible. Jack is different from the clown,? He has a strong purpose, and he is not impatient of loneliness. He has served a year and a half in Arkham,? There is no reason to suddenly desire freedom." Batman looked tired. He pressed the Jingming acupoint. "He's mentally ill,? Letting him out of surveillance is irresponsible to the citizens of Gotham. He must go back to Arkham."

Suddenly, as if he thought of something, he began to check the emails that Jack had received recently.For more than a year,? Jack has submitted papers to many academic journals, all handwritten on paper—because the most terrifying criminal in Gotham is prohibited from using computers—because of his special situation, most academic journals choose to respect him In the first eight months, Batman would review the emails to confirm that Jack did not take the opportunity to exchange information with the outside world to plot something. Later, Jack's law-abiding made him gradually give up. This job only requires the staff of Arkham Asylum to check and enter one by one.

Using precise search to filter out spam, several letters from Metropolis appeared on the bat computer, and Alfred read the words on the letters one by one, and read: "Elders difference problem, in any case only by 1 In the infinite sequence composed of and -1, a finite subsequence with equidistant between items can be found... Navier–Stokes?equations, the equation of motion for the conservation of momentum of viscous incompressible fluid, boundary The condition is a nonlinear sliding boundary condition, whether the solution exists and the uniqueness of the existence...From a smooth curve to an elliptic curve defined on the rational number field Q, the number of elliptic curves whose rank exceeds 21 is limited*..."

Batman silently slid across those bible-like symbols, and clicked on the last letter: "...Mr. Jack Arnold Christian, we sincerely invite you to do an interview with the editorial office of the Metropolitan "Mathematics" journal, and discuss Participate in the mathematics seminar held at the Metropolitan University from November 11th to 15th. This conference is organized by the Metropolitan University. In order to ensure the normal and orderly convening of the academic conference, please attend the delegates at..."

"November 11th..." Batman pondered for a while, "Ah Fu, book a plane ticket—forget it, I'll go directly by private plane. Inform Superman, if I remember correctly, the editorial department of the "Mathematics" journal, and " The Daily Planet isn't far away."

There was no hijacking, no explosion, no missiles, no terror/attack/attack, no sudden aliens, Jack put on a blindfold, took a nap, and arrived at the Metropolitan International Airport.

He walked out of the station carrying a small leather suitcase, and immediately saw the person who came to pick up the plane. The person was wearing a smoky brown coat, a lead gray long skirt, and his crimson curly hair was neatly combed. .She waved the card with her name on it, and shook hands with Jack who came forward: "Professor Arnold, with all due respect, you are younger than I imagined. I read your article about the Cayley–Bacharach property of elliptic cubic curves last year." When I wrote your thesis, I thought you were over forty."

Jack Arnold Christian, Jack's old name and pseudonym, he forged a resume through computer technology, in this resume, his identity is a professor of mathematics at Gotham University.

Jack raised his eyebrows: "Although it is cruel to say so, mathematics is a subject for young people."

"Your analysis of the NS equation is very fascinating. Abandoning the direct numerical solution method, using Reynolds transport theorem is to connect the Euclidean description*. Unfortunately, the academic circles have a lot of controversy over the process you gave, but it is undeniable that you have taken a step forward. Take the first step. At least our editorial department recognizes that you are the person who is most likely to solve the Navier-Stokes equation in this century." The lady who picked up the plane led him into a taxi while talking, "We Therefore, I invite you to be the cover character of the next issue of Mathematics."

Jack shrugged: "'The person most likely to solve the Navier-Stokes equation this century', this title changes every ten years—maybe five years."

"Are you going to talk about the NS equation in this interview?" The lady snorted and was amused by him.

"No, I still want to get back to my old job. Let's talk about elliptic curves. Maybe this can help us understand the tidal force under the strong theory of relativity." Jack made a gesture, rolled down the window, and admired the metropolis. landscape.

The biggest difference from Gotham, an industrial city, is that the metropolis feels brand new.If Gotham is an aging but still dignified lady, Metropolis is a youthful and lively beautiful girl.The mist that dissipates gradually in the morning intersects with the morning light, the sky is blue and blue, without the slightest shade of haze, velvety soft clouds dot the horizon, and are cut by the bright sunshine like broken gold, high-rise buildings It stands upright, like a giant nail inserted by the gods between heaven and earth.The light reflected by the mirror surface of the tall building is like fish scales, there is not a single stain on the wall, everything is bright and beautiful.Amidst the roar of the plane flying overhead, he saw a sculpture standing on the square, a man like an ancient Greek god carrying the entire planet on his back, with an expression like Jesus crucified on the cross.

Metropolis, a city guarded by gods on earth.

"Metropolis is different from Gotham, isn't it?" When he got there, the female editor helped him open the car door and said with a smile.

Jack smiled back: "It's nothing different, there is a lunatic with a salvation complex flying around between tall buildings."

He followed the female editor into the tall building, and suddenly, a subtle feeling of being watched climbed up his back, but he didn't look back to see who he was, and just got on the elevator with the female editor.His figure disappeared behind the elevator door, and a young male reporter looked back with some doubts.He has a muscular body like a marble statue in the Renaissance era. He wears a slightly cheap white shirt on the upper body, and black suit pants that are pressed neatly on the lower body.His facial features are three-dimensional and handsome, with a pair of round glasses on the bridge of his nose, and a bunch of iconic curly hair on his forehead.

Clark Joseph Kent, in addition to this name, he has a more widely known title: Superman.

"What are you looking at, Clark?" Lois Lane patted him on the shoulder.

"Hmm... just now, I seem to have seen someone I know." Clark pondered for a while, "Louise, I'm going to the bathroom."

He walked into the men's room, took out his mobile phone from his pocket, and was about to make a call when suddenly, a few slender and cold fingers rested on his wrist. He turned his head and saw a tall man with blue eyes standing beside him , wearing a luxurious hand-cut suit, smiling at him.He looked up and down this handsome and polite gentleman, trying to find out from him the shadow of the demonic green-haired lunatic, but he was tall, handsome, and personable. Horrifying, unempathetic eyes, he couldn't see anything.So he raised his eyebrows and said, "Joker?"

"It's Jack." Jack casually lit a cigarette.

"I didn't hear your heartbeat."

"Some frogs can stop the heartbeat when they are dormant at low temperature. I learned their skills." Jack smiled, and put a finger between his lips, making a "silence" gesture: "Don't call Batman, Let me enjoy my free life for a while."

Clark smiled, he didn't catch the buffoon at the first time, because he knew that Bruce's lone wolf complex was very serious, he had a kind of possessive desire for his city and his criminals, and he didn't allow others to intervene in his Job: "Otherwise you throw the laughing gas bomb in my face?"

Jack shook his head in disbelief: "Otherwise I'll tell Louise Lane about you being Superman."

Clark paused: "It doesn't threaten me."

"Relax, I didn't threaten you or your beloved lady reporter, meringue." Jack walked slowly to the door of the men's room, turned his head and smiled at him, took something out of his pocket and threw it to him, "When I walk out of this toilet, you can call Batman to catch me, but no matter when you come, please be quiet when I give an academic report, and at least have a gentleman's spirit of respecting knowledge, After all, I didn’t come out to play this time, that’s all.”

Clark took what he threw and found it was a cigarette.He looked up again, and the dark devil waved his hand with his back turned to him.

"...for a Lie group G (or a finite-dimensional semi-simple Lie group), call the smooth map f:Rn→Gf:Rn→G from Rn to G an element in the gauge group C. The gauge group refers to all Rn Smooth mapping to G. Let V be an n-dimensional Euclidean space with an inner product metric, select the unit orthogonal basis {e1, e2, ..., en}, and the Euler-Lagrange equation of the Yang-Mills functional is DAFA=0DAFA =0, its Grassmanian algebra is recorded as *..."

Suddenly, a knock on the door interrupted Jack's words. He and the editor turned their heads together and saw a tall and strong man standing at the door.Jack looked at the face that often appeared on Gotham TV, and the clean and beautiful blue eyes, and couldn't help but sigh at the end of his free career. Bruce Wayne interrupted them by tapping on the door frame with his fingers curled Talk, and then say to the editor: "The editor-in-chief let you go."

The editor froze for a moment, then apologized and left.

As soon as he was gone, Jack collapsed deflated on the chair, slid down like wax melted in the heat, and sighed in frustration.Bruce walked up behind him, squeezed his shoulder like a massage, and patted him hard.Jack didn't move, looked up at him, only the ceiling and Bruce's face in sight, and said, "Can't you come later?"

"Prison escape, huh?" Bruce said meaningfully, "and broke a lot of guards' bones, huh?"

"You can't lock me up all the time. I've been in Arkham Asylum for too long. If I have no mental problems, I will have problems. And they didn't die, but they may have to lie on the hospital bed for several months."

"You come here to give an academic report, and "Mathematics" plans to use you as the cover character of the next issue-do they know that your resume is all forged? Professor Jack Arnold Christian, who majored in laughing gas at Arkham University?" Bruce, who wasn't wearing a Batman mask, said a lot. He took out the handcuffs from his pocket and grabbed Jack's wrist.

"Bruce Wayne from Gotham, you have a strong will to overcome your sense of humor, welcome to the Killer Corps." Jack rolled his eyes, "I said, don't disturb me when I give an academic report, you don't keep rule."

"First, there are no rules like yours; second, don't mess around."

"And handcuff me now? Just when I'm halfway through my theory? Dude, can you at least wait until I finish taking pictures?" Jack rolled over on his chair, "There's still afternoon I was going to give a report on the continuation of Sobolev space, but now you have ruined it all."

Bruce hesitated for a moment. Jack thought he was an ordinary person. He was imprisoned as a felon in Arkham for more than a year. .If Jack escaped from prison and came to Metropolis only to participate in academic-related activities, then it is a bit unreasonable to arrest him here. Besides, Jack is more obedient than the clown, so he should be trustworthy.So he put the handcuffs back in his pocket and said to Jack: "In that case, let's wait until you finish taking pictures."

Jack responded, and Bruce turned around, wanting to go outside the door and wait for Jack. Before he had walked a few steps, he heard the sound of glass being smashed behind him.He turned around abruptly, Jack was gone, the window was open, the off-white linen curtains were blown away by the wind, and there was only a large hole in the floor-to-ceiling window that was as tall as a person, and a few black footprints remained beside the window, Broken glass shards littered the floor, and the afternoon sun shone in, hazing his blue glasses.Bruce threw himself on the window sill and looked down. The tall, lanky man, wounded in the fall, was limping across the street with a limp leg, his dark figure like the shadow of a tree.He staggered and disappeared into the shadow of the dark high-rise building, like a madman who had reached his end.

There was also a note on the table, scrawled and obviously written in haste:

You broke the rules first (You? broke? the? rules? first)!
