In the early summer of May, the sun is bright in the sky.
The sunlight was blocked by the trees beside the sidewalk, leaving only a few spots of light on the ground.
But even so, people still feel unbearably hot when walking on the road. This is summer in Star City. Africans have to shed their skin when they come back from summer.
At this time, a mother and son were walking on the hot sidewalk.
The teenage boy Qiao Ze looked dull and his walking posture was a bit weird. The mother Lu Xiuxiu next to him glanced at the boy from time to time and kept mumbling.
"Qiao Ze, do you want to let people know when you meet Teacher Yu? This is a matter that affects your whole life. Mom is useless and can only help you. If it doesn't work this time, you may not be able to go to college. Now, what will you do then?"
Unfortunately, Lu Xiuxiu's nagging did not resonate with the young man, and he did not respond. His face still had a calm look on his face.
"Hey... you!" Lu Xiuxiu wanted to say a few more words, but seeing the child's dull expression, she finally gave up, but she still kept mumbling.
Fortunately, the hotel that held her last hope was not far away.
…
Xiaoxiang Xingfu Hotel, Room 716, Li Jiangao was leaning on the bedside and carefully looking at a printed paper. The sudden ringing of the doorbell interrupted his thoughts. He frowned slightly and put the paper away. put it on the bedside table and walked to the door.
"Teacher Yu, I am Qiao Ze's parent. Teacher Zhou introduced us here."
Oh, I'm looking for Lao Yu. It's approaching the admissions season, and the admissions teachers are really busy.
"This parent, I don't..."
Li Jiangao smiled bitterly and opened the door. He was about to explain that Lao Yu had changed rooms with him, but the woman started talking about it.
"Teacher Yu, I know this is not easy to handle, but please listen to what I have to say first! In this way, let's go in and talk..."
Before she could finish her words, the woman grabbed the hand of the boy next to her and rushed into the room...
Li Jiangao was stunned. He had no choice but to understand the current Internet culture. He subconsciously avoided physical contact with the woman in front of him, but he just dodged sideways, and the woman successfully pulled a rather dull-looking child into the room.
"Um, I'm not Teacher Yu. Teacher Yu lives on the fourth floor, in..." Li Jiangao turned around with a wry smile and continued to explain.
However, the woman seemed not to understand what Li Jiangao was saying at all, and spoke to herself: "Really, Teacher Yu, I'm not boasting, our Qiao Ze is really excellent, he can often get full marks in mathematics and physics. Yes, it’s just that the scores in Chinese, English and other subjects are a little worse.
Originally, he could have been recommended to Huaqing and Yanbei by participating in the Olympiad, but the child had a dull temper, was not good at communication, was excluded by the people inside, and was forced by the single coach in the school not to participate in the competition, but this year we ourselves I helped him sign up for a competition in the city and even won an award. I brought all the certificates. Look..."
Li Jiangao felt a little broken looking at the chattering woman.
If I had known that there would be such a difficult parent who didn't understand human language today, I shouldn't have changed rooms with Lao Yu last night.
"No, parent, I won't lie to you, I am really not Teacher Yu. Last night..."
When Li Jiangao continued to try to make the other party understand the meaning of his words, the woman suddenly broke down and cried: "Teacher Yu, really, you are our last hope. No one I can find during this time is After searching, the child's class teacher was actually very optimistic about Qiao Ze, but the child was really partial to subjects.
Qiao Ze's father died early, and I raised him alone. The doctor said he had Asperger's syndrome, but in fact he was not sick, he just didn't like talking to people. Think about it, if a person with such a dull temperament cannot go to a good university, what else can he do in the future? !
I'm begging you, why don't you give him a test, as long as it's in mathematics or physics. It doesn't matter how difficult the question is, the harder the better. If he can't do it, I'll turn around and leave! Really, our Qiao Ze is really a genius! "
Li Jiangao was completely stunned.
At this time, he was so embarrassed that he could dig out three rooms and one living room with his toes on the floor, and he secretly prayed that the soundproofing of this hotel would be better. Otherwise, the people around her wouldn't be able to hear clearly what this woman was saying, and God knows what the professors living nearby would think.
But this woman is still a widow!
What the hell is this!
"Qiao Ze, you also say hello to Teacher Yu. Hey... don't touch the teacher's things!" the woman said, wiping her tears.
Only then did Li Jiangao realize that there was someone else in the room.
When he turned his attention to the child, he realized that the mother was already crying, but this Qiao Ze was still as calm as an outsider. And at some point, this guy picked up the paper he threw on the bedside table. He was sitting on the sofa next to the bed, watching silently.
Just as Li Jiangao was about to speak, the young man suddenly raised his head and glanced at him. Only then did he notice that the child's eyes were particularly clear, but the young man's next words stunned him again.
"Is this an article you wrote?"
Li Jiangao shook his head subconsciously and said, "No, this is the latest paper by Professor Ronil from the University of Illinois."
"Oh! The author is quite smart..." The young man nodded and commented, but then immediately added: "But the third lemma was proved wrong, so subsequent proofs have problems."
Li Jiangao was so angry...
Look what this says...
This is a paper published in the "Annals of Mathematics". It has been reviewed by a group of mathematicians. Of course, there may be problems with the paper, but a group of reviewers in the same field have not noticed it. Can this guy see it?
Moreover, this paper is about group theory, and you can understand it no matter how obscure it is.
For those who don’t understand, I’ve probably never even heard of this word.
Not to mention a high school student, he was tortured by the topic selection of group theory during his doctoral period.
But after all, Li Jiangao was just an associate professor and he still had some accomplishments, so he just sneered and said, "Haha, what's wrong? Can you briefly explain?"
"The proof is correct in three-dimensional conditions, but it is wrong to bring it into the four-dimensional Euclidean. If you bring in the general formula of the four-dimensional straight line equation for analytical calculation, you will get a unique solution, which means that either the hyperplane ABC is 0 at the same time; or this The surface of the subspace will intersect the customized line at the coordinates of the solution. However, in three-dimensional Euclidean geometry, ABC cannot be 0 at the same time; in four-dimensional geometry, the surface and the straight line will not intersect."
Li Jiangao was stunned for a long time, then rushed over, almost snatched the paper from the child's hand, and then began to carefully re-read the proof of Lemma 3, and then looked at Qiao Ze with a strange expression: "How do you know this part? Does the equation have a unique solution?”
Qiao Ze curled his lips and looked at the man in front of him as if he was still looking at a fool, with a hint of disappointment. He didn't want to answer at first, but thinking that he was the first person who could understand what he meant, he still reluctantly gave it. Explanation: "Of course it is estimated. You imagine the three-dimensional projection in the coordinate system, then use the coordinates of each point as a parameter, and then bring it into the dimension conversion calculation process. Although I did not calculate the exact result, but I am certain that this equation has a solution."
"In short, the special type of compact Lie group the author is trying to construct is flawed!"
