In the building of the Academy, a conference room was arranged as the site of the defense meeting.

A long table sits three people, who make up the defense team.

A DV will be set up at the site of the defense meeting, equipped with a powerful sound receiving equipment, and the whole process of the defense will be recorded and archived.

Dissertation defense, this is a very important and rigorous thing, Yan University School of Mathematics does not allow any illegal fraud, Yan University of Mathematics Institute diploma must be genuine.

Shen Qi strode into the scene of the defense meeting.

Momentum, momentum is important.

Entering the room and closing the door, Shen Qi turned around and took a look, and the three experts in front of him looked directly at him.

The old man in the center has a kind face, and there is a card on the table: Long Weihua.

Long Weihua is the head of the Department of Mathematics, the leader of the defense team, and the main defense teacher.

Director Long is the main defense teacher, Shen Qi is at least not panicked, he knows Director Long and has dealt with him several times.

The other two teachers, one surnamed Ma and the other surnamed Xiong, are both professors of the Academy of Mathematics, Shen Qi has heard the name but has never seen him.

The combination of the three teachers in the defense group, Ryoma Bear, is very strong.

Shen Qi's most familiar teachers, namely the teachers of Gao Dai, Shufen, and Jieji, Professor Sun, Professor Lu, and Professor Qu, did not enter the defense team.

Shen Qi's defense paper was submitted to the defense team last month, and Long, Ma and Xiong had 20 days to review the paper and outline the questions.

The three defense teachers all have senior professional titles and are in line with the dissertation defense process.

"Shen Qi, let's introduce myself first. Director Long presided over the defense meeting and made a very regular opening remarks.

"Okay. Shen Qi specially wore a suit today, he attached great importance to this defense meeting, and entered in the most solemn clothes of a man.

Shen Qi put on his suit, he behaved generously, calmly and said with a smile: "Good morning, teachers, I am Shen Qi, a first-year student in the Department of Mathematics. In high school, he won the championship of IMO and CPhO, received a perfect score in the college entrance examination, and published a mathematics paper in the "Mathematical Innovation News". ”

"Since I entered Yan University, I have made certain achievements in my studies, and among the eight courses that have been completed, seven have received full marks and one has scored 97 points. He has published 6 mathematical papers in national core journals such as "Mathematical Review" and "Journal of Mathematical Research", including 4 Chinese core papers and 1 SCI. ”

"At the same time, I took the initiative to serve as the head of the Mathematics Department, and in my daily study and life, I was able to unite my classmates, respect my teachers, and actively participate in various activities within the school. ”

"There is no end to learning, and today I have the courage to apply for undergraduate dissertation defense, just to make further progress and forge ahead on the road of mathematics. That's the end of my introduction, thank you. ”

Shen Qi's self-introduction is concise and powerful, confident and generous, and fluent in language organization, and within two minutes, he expresses his main characteristics and achievements, seeking truth from facts, and not bragging.

The three defense teachers nodded, this link was successfully passed, Shen Qi's language skills are strong, no problem.

+1 language experience

The system flashes out a message.

Making a qualified speech on an important occasion can increase the language experience value.

"Okay, let's move on to the respondent's statement, and ask Shen Qi to finish your statement within 15 minutes. Director Long made a gesture of please.

This kind of gets to the point.

If you introduce yourself well, you may get some impression points.

Starting from the respondent's presentation, the respondent's on-the-spot performance is directly linked to the academic score.

This link is very important, Shen Qi should clearly express the key elements of his thesis such as the topic background, core content, views, and value outlook in a limited time with an unhurried speed and clear sentences.

It is definitely not possible to read the paper once, Shen Qi's final paper has a total of 24 pages, and it is impossible to read it in 15 minutes, and the difficulty of reciting mathematical formulas is better than tongue twisters.

The key is to read the paper according to it, which is also too lo, and there is nothing to force it to speak of.

The real big bulls make speeches that are unscripted and come casually.

Shen Qi brought a paper and put it on the table, he looked at the three defense teachers, and began to state: "The title of my paper is "Analysis of Generalized Nonlinear Complementarity Problems Constrained by Linear Inequality", and the instructor is Professor Sun Erxiong of the School of Mathematics. ”

Based on the generalized Jacobian matrix of semi-smooth equations composed of generalized complementarity problems, the generalized nonlinear complementarity problems constrained by linear inequalities are analyzed. ”

"Director Long, Mr. Ma, Mr. Xiong, you are all authoritative experts in the industry, so I won't be verbose and talk about the key points directly. ”

"We all know that the problem of generalized nonlinear complementarity is a classical problem, which Newton has been studying since his time. ”

"So in the 21st century, is there any point in us continuing to study this topic, and what is the point?"

My answer is, it makes sense. ”

"After more than a semester of hard work, I continued to explore and construct the problem into a system of semi-smooth equations, and introduced the L2 norm of the equation system, so as to design and describe a new algorithm to solve the generalized nonlinear complementarity problem of inequality constraints. ”

"So, my topic was very interesting, and I came up with a new algorithm. ”

"Seeking innovation is becoming more and more difficult in contemporary mathematics. ”

"But we have to innovate, or mathematics will die one day. ”

"New wine in old bottles is also an innovation. ”

"I'm going to spend 10 to 11 minutes talking about my new wine. Yes, it's a good bottle of wine, not expensive, but strong enough. ”

"The first thing to discuss is the algorithmic problem, and you can review page 5 of the paper, the relevant properties of δf, and the redefinition of the properties of directional derivatives and semi-smooth. ”

……

Shen Qi spoke loudly, without a pause within 15 minutes, and he knew the paper he wrote by himself.

Director Long, Teacher Ma, and Teacher Xiong each had a copy of Shen Qi's paper, and they kept flipping through it, reading and listening, and unconsciously entered the rhythm of Shen Qi's discourse.

This shows that Shen Qi speaks well, and his speech has a certain appeal, which can make the audience quickly enter an academic state instead of sleeping. The defense teacher is also an audience, a special audience.

In Shen Qi's Respondent's statement, the most frequently used terms are semi-smooth equations, generalized nonlinear complementarity, local linearized approximation, quadratic models, etc.

In a discourse or presentation, the central idea or core idea is particularly important.

Skilled speakers will instill a few key keywords over and over again, so that the audience will naturally get to the point.

Shen Qi closely followed the topic and core keywords, and the arguments in the respondent's statement were smooth and logical.

The three defense teachers kept nodding, it made sense, and there was nothing wrong with it.

"With all that said, my statement is complete. ”

Shen Qi pinched the time very accurately, no more, no less, just 15 minutes, he had practiced many times before.

"Very wonderful presentation. Director Long expressed his approval.

"Thank you. Shen Qi was always smiling, and he had a good start.

"Do you need to rest for a few minutes and drink some water, Shen Qi?" Director Long asked kindly, "Once you enter the Q&A session, you will be asked to answer immediately." ”
