Chapter 445 Is It Him?
The first lecture room is the largest lecture room at the forum. It can accommodate a full 500 people!
But at this moment, the seats are already packed!
Even the aisle was packed with people. People in the back were standing, and people in the front brought their own small benches. It was completely blocked!
Katarina and Shekov felt a little unlucky at first, not being able to get a good seat. Looking back, they felt very lucky, because people kept coming in a hurry in the corridor, and if they arrived a little later, they would have to crowd outside to listen!
"Why are there so many people here?"
"Gold Medal Winner, Question No. 50. A total of 6 questions have been solved in this forum. This one is at the top. Why do you think there are so many people?"
"Looking forward to it! This year, there are some mid-level questions that have been solved!"
"It may not be able to be broken. Haven't we mentioned this yet?"
"The gold medal winner took action and basically didn't run away!"
The atmosphere on the field was warm, and the faces of many mathematicians were glowing, just like the audience waiting for the show to start!
Finally, applause started from one corner and spread quickly!
Katarina and Shekov stretched their heads and saw a goat-faced man entering from another entrance, holding a laptop in his arms and squeezing through the audience toward the podium.
With thunderous applause and the attention of the whole audience, gold medal winner An Yulong appeared on stage!
"That's what a real man should do!" Shekov said an old saying excitedly.
"What do you mean?" Catalina had never heard of it.
"It means this is what a great person should be like!" Shekov said, "Look at this aura!"
Catalina smiled, "If we can solve problem 50, we will have more aura than him!"
"This version of yours is called Pike instead!" Shekov said with a smile, "I'm jealous, Song He has such an awesome mentor!"
Catalina nodded silently. She was really envious of a tutor who could win a gold medal at the International Mathematics Grand Prize and a tutor who could solve the 50th question on the problem wall in just a few days. Who wouldn't envy him?
Finally, An Yulong stood on the podium and connected his laptop to the projection equipment.
“Thank you very much for your support!”
"The content of this lecture is question 50 on the question wall. I will announce the complete steps and answers one by one!"
"However, before announcing it, I want to make a statement in advance!"
"This question was not solved by myself, but by a scholar who was not at the forum, thousands of miles away!"
"He asked me to announce it on the forum and sent me the complete steps. I read it hastily. The general idea is OK, but whether the details can withstand scrutiny depends on your sharp eyes!"
"I won't announce the name of the real problem solver for now. If I talk about it later and everyone finds that the solution is wrong, then I will save him face and avoid embarrassment. If everyone thinks there is no problem after I finish talking, I will Reveal the real problem solver!”
After speaking, An Yulong bowed lightly.
There was thunderous applause again. Everyone heard that An Yulong was going to talk about the fiftieth question, and their subconscious reaction was that he had solved this question.
At this moment, when they learned that it was not An Yulong who had solved the problem, everyone was not disappointed, and they were still in high spirits. A scholar who can communicate with the gold medal winner, and who can let the gold medal winner personally help give lectures, is an extraordinary person!
In the aisle in the corner of the back row, Shekov and Katarina looked at each other with a look of surprise on their faces!
"No...it can't be right?" Shekov asked.
"Probably not." Catalina shook her head.
The two played a riddle, but both understood what the other was talking about.
A few days ago, they contacted Song He to solve problem 89 together. Song He refused, saying that he would try to solve problem 50!
At this moment, An Yulong suddenly claimed that he was not the one who solved the problem, and that someone else had a master. The first reaction of the two people was, could it be Song He who solved the problem?
This thought made the two of them tremble with fear, but when they thought about it calmly, the probability was not high.
Although Song He is strong in mathematics, he must not be that strong, right?
The two looked at the big screen uneasily, and a handwritten problem-solving process was projected.
The handwriting is quite sloppy, more arrogant than the prescription written by the doctor. It can be seen that it is caused by the inability to keep up with the hand speed when inspiration breaks out.
Shekov's face changed slightly, he stared at the handwriting on the big screen carefully, and pursed his lips.
Catalina nudged him with her elbow. "Is that his handwriting?"
"I can't tell..." Shekov hesitated, "It's a bit similar, but it's only vaguely similar. I've never seen his manuscripts so sloppy before."
Catalina nodded, "Then it shouldn't be his."
The two of them were uneasy. They didn't know why. They thought intellectually that it couldn't be Song He, but intuitively they felt more and more that it was him!
On the stage, An Yulong spoke into the microphone and explained the steps.
The gold medal winner's lectures are indeed very good. The explanations are very meticulous and the ideas move forward step by step without any jumps. Basically, the audience present can understand it as long as they are not behind in knowledge and listen carefully.
"Here the symplectic homeomorphism is the image of the tangent map of the C function, which must be symplectic to the identity map, and what is D? The set of zero sections of the cotangent bundle! Therefore it must be a Lagrangian manifold!"
"When H is a compact symplectic manifold, H2 is a time-dependent Hamiltonian, that is, a real-valued smooth function, and then the Hamiltonian vector field of Equation 4 can be obtained..."
"Suppose B is a Riemann surface, then the Riemannian metric and the complex structure jointly define the volume form, which is the canonical symplectic form on A above. It is easy to know that δ is the Liouville form on M..."
In the huge venue, there was a series of rustling sounds of pencils making rapid calculations on the paper.
The sound effect of the entire venue sounded like strands of fine sand constantly pouring down from the ceiling.
There were gasps from time to time in the back row. Someone was doing the math and was frightened by the ingenious problem-solving ideas!
"What a stroke of genius!"
"This step is powerful enough and uses very basic knowledge, but most people would never think of using it."
"I'm convinced, this person is so smart that he's almost a demon!"
"God! Why did you give me such a bad brain? Why did you give other people such good brains?"
Shekov and Katarina were also busy calculating.
Neither of them said a word. Their faces were as dark as water.
To be fair, they all knew the knowledge used to solve the problem, but they never expected that they could use it so cleverly!
The more they calculated, the more they became deeply in awe of the author of the steps to solve the problem!
The suspense now is, who is the true identity of the master who solved this problem?
