Chapter 54 If you have any questions, please come to Teacher Lu (Please read on!) Ma Lijuan looked at Lu Shan with suspicion. Is this person a teacher? He is quite tall, has thick hair, is handsome, and dresses rather simply. But this was too much for him to bear when he saw the lewd look on the face of the senior sister with glasses. Like an older sister, Ma Lijuan quickly protected Qiao Weiwei behind her, looked at Lu Shan vigilantly, and then looked at the note in Lu Shan's hand. This guy actually asked a girl for her phone number in the library, so openly! Ma Lijuan seriously suspected that Qiao Weiwei was too stupid in socializing and was probably being cheated. This guy wasn't a teacher at all, he was clearly an LSP. Lu Shan stood there awkwardly, still holding the girl's note in his hand. "Qiao Weiwei, thank you for your library card. I have returned the borrowed books." Lu Shan has a good memory and can remember girls' names.
Qiao Weiwei saw what Lu Shan looked like now. "It's okay. Thank you for helping me revise my paper. It has been approved by my supervisor after preliminary review." "By the way, this is my classmate Ma Lijuan. Teacher, please see if it's convenient for you. If it's convenient, please take a look at her paper." Ma Lijuan still didn't believe that Lu Shan was a teacher. Lu Shan has nothing to do with the teacher in terms of appearance or temperament. Ma Lijuan immediately asked: "What is the Calabi conjecture?" Lu Shan laughed. What the hell, this is not a blind date, but there is still a test. "For any Kähler manifold of complex dimension n and any complex orientation, there exists a function u and a new Kähler metric g, which can be expressed as follows..." Ma Lijuan asked again: "In Xiamen theory, what is a classical group and what is a Lie group?" Lu Shan blurted out: "If we add some restrictions to the linear transformations (or their matrices) in GLn(K), we can get some important subgroups of GLn(K), for example, all linear transformations with determinant equal to 1... More generally, by taking all linear transformations that keep a bilinear or semilinear form unchanged, we can get many similar subgroups of GL(K). These subgroups are called classical groups. Classical groups are either simple groups or close to simple groups. For example, we can get a simple group by taking the quotient of a subgroup formed by an appropriate scalar matrix. If K is the field of real numbers or the field of complex numbers, the classical group becomes a Lie group." Just kidding, Poincare is the founder of topology! Ma Lijuan nodded. She had studied some basic mathematical concepts and was sure that Lu Shan should be in the mathematics department, or at least a graduate student, but she was not sure whether Lu Shan was a teacher. Qiao Weiwei rolled her eyes. She took out the paper from Ma Lijuan and handed it to Lu Shan, "Teacher, please take a look." Then Qiao Weiwei looked at Ma Lijuan angrily, meaning that Ma Lijuan was looking for trouble. She had finally met a teacher who was kind, gentle and willing to teach her. If she offended him, it would be difficult to write her thesis in the future. Ma Lijuan muttered softly, "She looks younger than us, so she doesn't look like a teacher." Lu Shan didn't care about these details because he knew the points were coming. Lu Shan: "Lie groups and group-invariant solutions accepted by two types of broken group equilibrium equations?" "The skeleton has just been built?" “The approach of this paper is very good and has strong practicality in industry and medicine.” This is good! Should be able to contribute a lot of points.
Lu Shan said: "You should have understood the previous ideas clearly, so I will not explain them again. I will tell you about the latter part, starting with the classification of sub-Lie algebras of Lie algebras L3 and L4." Ma Lijuan's paper is concise and to the point. As long as you have clear ideas, the paper is actually very easy to write and you don't have to write much. The most important thing is that this paper is very practical. It is not just a purely theoretical analysis and has excellent application prospects. Lu Shan spent a full hour explaining the ideas of the paper to Ma Lijuan. When he encountered some difficult points, he would explain them in detail and write them down clearly in his notebook. Ma Lijuan initially thought that Lu Shan was most likely a graduate student in mathematics, but as Lu Shan carefully explained some details of the thesis, she felt that she had wasted the past two years of studying, and that Lu Shan's theoretical level must be above that of a graduate student, and he must be a teacher the school had just recruited. Maybe he still has a doctoral degree and came to Jiangzhou University because he was given a settling-in allowance. In front of Lu Shan, Ma Lijuan felt like a poor student. Lu Shan spoke very fast in some places. When he saw that Ma Lijuan seemed to understand but not quite, he would deliberately slow down his speed and then explain it in detail again. Ma Lijuan was very touched. She wanted a teacher like this! [Points: +3] Lu Shan also breathed a sigh of relief, the points finally came. But this efficiency is still too slow, and the students are about to have winter vacation, and the library will be closed at that time, so there is no way to earn points. So Lu Shan wrote his email address and QQ on a piece of paper and handed it to Ma Lijuan, asking her to contact him anytime if she had any questions. This way, he can earn points even when the school is on winter vacation. "Thank you, teacher!" Ma Lijuan carefully put away the note, "May I ask your name, teacher?" If I think of myself as a teacher, will more students trust me and ask for my advice? "land." "Teacher Lu, I'm sorry to bother you with the thesis! There was some misunderstanding just now, please don't take it to heart. I'll buy you milk tea right away. Do you like matcha flavor or strawberry flavor? Ma Lijuan's personality is completely different from Qiao Weiwei's, she's a bit of a social bull. Qiao Weiwei rolled her eyes. Matcha and strawberry flavors were both Ma Lijuan's favorites. The senior sister with glasses who just misunderstood Lu Shan was also very embarrassed. She didn't expect that Lu Shan was actually a teacher. I didn't expect that Lu Shan's academic and teaching levels were very high, and what he taught was profound and easy to understand. The senior student with glasses embarrassedly took out her paper and asked: "Teacher Lu, just now you told me which setting I made wrong." Lu Shan starts speaking in domineering mode! Ma Lijuan took out her cell phone, opened QQ, and sent a message to the QQ mathematics graduate student group (where no teachers were present), "Everyone! Everyone! Great news! The new teacher Lu from the School of Science is on the sixth floor of the library and is very kind!" "He explained the thesis to Qiao Weiwei in detail, and Qiao Weiwei's thesis was passed by Thanos (Chen Qiyi) in seconds!" "He just explained the thesis to me in detail. It was like an epiphany for me. I think I can pass it if I follow his ideas." "Everyone, hurry up and come to the 6th floor of the library. We don't know when Professor Lu will leave. Winter vacation is coming soon. If you don't want to be tortured by the thesis during the Spring Festival, hurry up and ask questions!" The QQ group exploded immediately! The graduate students who were troubled by their thesis became excited all of a sudden. "I'm going, is it true?" "The new teacher is so awesome that his papers are instantly passed by Thanos?"
"Here I come. In order to have a good Spring Festival, I will try to finish the paper in the next two weeks." "Is this the rescuer sent by God? Lijuan said it's good, so there's absolutely no problem." This side of Lu Shan. [Points +2] I accidentally gained 5 points. He didn't expect that the graduate students would come. 感谢“朱二娃80”2张月票，“婺江人”2张月票“书友7745”2张约炮，“慌生下”“剥橙”1张月票。 Thank you all for your recommendations!
