"This ...... I'm really sorry, I didn't expect ......," Duan Yun said apologetically.

"Duan Yun, I know that it is indeed very difficult to write this kind of paper, but you have to try something, right? Didn't you also successfully crack the Hodge conjecture before?" Jiang Chengdong frowned when he heard this, and then said: "Look, I have found all the people for you, and everyone is here to help you." ”

Jiang Chengdong didn't know that Duan Yun had completed his thesis, and thought that he wanted to give up this paper, and he was a little unhappy in his heart, after all, he also took a certain risk to gather all the top mathematicians in the school, but what he never expected was that Duan Yun decided to quit before it officially started, which was equivalent to letting him spend a long time in vain.

"President Jiang, I originally wanted to rely on everyone's help to write this paper, but ...... I really didn't expect ......," Duan Yun pouted and said.

"Duan Yun!" At this time, Guo Haitao on the side also spoke, only to see him frowning and saying: "There is nothing easy about engaging in academics, any valuable academic achievements in history are the results of those senior scientists who spent a lot of time and energy to obtain, if you only encounter a little difficulty and retreat, then you are destined to have no great achievements in this life!"

Guo Haitao was obviously also very dissatisfied with Duan Yun's attitude.

As Duan Yun's master, Guo Haitao naturally sincerely wanted to help Duan Yun.

Generally speaking, Guo Haitao, who has been burdened with the national military cryptography research project all the year round, has no distractions, except for work, almost never participates in any activities held by the school, and this time after receiving the notice from the principal Jiang Chengdong, he also temporarily stopped the work at hand for the first time, ready to help Duan Yun complete the writing of a new thesis.

In the final analysis, Guo Haitao is still a little selfish this time, he loves talent, for Duan Yun, Guo Haitao likes it from the bottom of his heart, not only because of his extremely high mathematical talent, but also because Duan Yun is also very sophisticated and calm in thinking and doing things, which is very rare for a young man who is not yet twenty years old!

As for the current public opinion that Guo Haitao has no children under his knees, accepting Duan Yun's apprentice is actually treating him as a godson, for this point, Guo Haitao does have such a little thought, this is not that Guo Haitao wants to stay, but wants to let himself have a successor to the mantle of what he has learned, from the current point of view, Guo Haitao can not find a more suitable candidate than Duan Yun, because as a doctoral supervisor of the Department of Mathematics, although the graduate students under him are far more educated than Duan Yun, but compared with Duan Yun in terms of talent, it is simply a difference, after all, mathematics is a subject full of mysteries, and if you want to become a real mathematician, in addition to having a solid theoretical foundation, the most important thing is to have a very high spirituality and understanding, in this regard, Duan Yun is undoubtedly a very rare mathematical genius!

"Director Guo, it's useless for you to say this. At this time, the corners of Professor Meng's mouth were hooked, and he said to Guo Haitao: "You also heard what your apprentice said clearly just now, it's not that we don't help your apprentice this time, it's really that he doesn't use it himself......

"Actually, I think it's good that Duan Yun can have such self-knowledge. At this time, the lecturer of glasses also suddenly interjected, only to hear him say with a smile: "Since Duan Yun has decided to quit from the beginning, this is also good news for everyone, after all, everyone is so busy with teaching and scientific research now, saving everyone's time and energy......

"That's right!"

That's right, Duan Yun is really wise to do this. ”

As soon as the lecturer's voice fell, several other people at the scene echoed.

"Hey......" Seeing this scene, the principal Jiang Chengdong sighed, and had to say helplessly: "Okay, since Duan Yun has decided to quit, then why don't you ......disperse?"

"Wait a minute!" Duan Yun hurriedly interrupted Jiang Chengdong's words when he heard this, and said, "I still have something I want everyone to help with......

"Duan Yun, what do you mean?" Professor Meng suddenly looked displeased when he heard this, and only heard him say in a serious tone: "Are you treating everyone as a monkey? Can I tell you, although you have indeed achieved a little academic success, but in terms of age and seniority, the one here is not your seniors and elders, this time we came to help you out of love, but you said you don't need help for a while, and now you say you need help, are you treating us as your subordinates?"

"Old Meng, what you said is a bit ugly. Jiang Chengdong frowned when he heard this, and then said: "Supporting talented junior students has always been our Huaqing's educational purpose, since Duan Yun has asked for us, no matter what aspect it is, we should be obliged." ”

Jiang Chengdong obviously still wanted to curry favor with Duan Yun, after all, compared to the others here, he knew Duan Yun's background best.

"Duan Yun, if you need help, just say it. Guo Haitao paused, and then said, "Have you chosen a good topic for your paper this time?"

"It's chosen!" Duan Yun raised his eyebrows when he heard this, and said, "The title of my paper is "The Argument for the Riemann Conjecture......"

"Riemann conjecture!?"

As soon as Duan Yun's words fell, everyone at the scene couldn't help but exclaim.

Anyone who studies higher mathematics is familiar with the Riemann conjecture.

The Riemann conjecture was proposed by the mathematician Riemann in 1859.

At the Second International Congress of Mathematicians, Hilbert proposed 23 mathematical problems that mathematicians should strive to solve in the 20th century, which are considered to be the commanding heights of mathematics in the 20th century, including the Riemann hypothesis.

The Riemann hypothesis is also one of the top 10 mathematical problems in the world that the Clay Institute of Mathematics is currently rewarding.

However, in the opinion of the vast majority of mathematicians, compared with the Hodge conjecture and several other top ten problems in the world, the Riemann conjecture is more difficult to solve, and it is not an exaggeration to say that it is the most difficult mathematical problem in the world to prove!

Everyone present, including Guo Haitao, thought that Duan Yun should choose one of the top ten problems that was relatively easy to choose this topic, but what they never expected was that Duan Yun actually directly chose one of the most difficult ones!

"Duan Yun, let me ask, how difficult do you think the Riemann conjecture is compared to the Hodge conjecture you cracked before?"

"Hmm...... I feel that the difficulty of this Riemann conjecture should be much higher than that of Hodge's conjecture, because this conjecture involves more advanced mathematical theories, and it requires a lot of calculations, so it is very difficult to solve......" Duan Yun said after a deep sigh.

"Since you understand the difficulty of this question, why did you choose this thesis proposition, don't you think you are a little too confident?" Professor Meng said with a look of disdain as the corners of his mouth hooked.
