The most important solution has passed, and next, just follow the steps.

Pang Xuelin wrote slowly on the whiteboard.

...

[The analytical solution of Einstein's gravitational field equation is divided into spherical symmetry and states. The analytical solution of the field equation can be given by the simple relationship corresponding to each integral value of parameter n. Due to the physical correlation of the solution, the pressure and density are both finite positive values, p/p and dp/dp should all decrease along its center to the surface of its structure. The line elements of the mean equation are: ds^2=g00dt^2+gk1dx^kdx^1;g00=e^γ,g11=e^a,g22=-r^2;g33=-r^2sin^2θ,gk1=0…]

...

[For n=1, the solution is always equal to the fourth solution of tolman. For n=2, when it is at the center of the sphere, p/p has the maximum value. Otherwise, the value of p/p decreases with the increase of r. The two solutions of n=1, n=2 have no regular characteristics for dp/dp and are not applicable to neutron stars. For all values ​​of n=3, u, the value of p/p decreases with r increases, and the maximum ratio of center to surface density p0/ps=4.5. To sum up, for Einstein's gravitational field equation ruv-1/2guvr=8πg/^4xtuv, its analytical solution is as follows...]

...

Solved solution!

Pang Xuelin dropped the marker and turned around and said, "This is the entire process of Ponzi geometry to solve Einstein's gravitational field equation. This method can be generalized to all problems of solving nonlinear partial differential equations. Of course, the emergence of analytical solutions does not mean that all nonlinear equations have accurate solutions, but there is no doubt that by solving the analytical solutions of nonlinear equations, the accuracy of the exact solutions of nonlinear equations can be greatly improved."

Wow

The auditorium was quiet for a while, and soon, applause rang out, sweeping the audience.

Everyone stood up and expressed their respect to the young figure on the stage.

From now on, physics, chemistry, biology, computer, engineering, machinery, economics and even social sciences... wherever models need to be established through nonlinear partial differential equations will undergo major changes due to the emergence of Ponzi geometry.

"After today, Professor Pang may become the well-deserved number one person in the mathematics world!"

Jagbus Dix Road.

"It's almost done. I didn't expect that a young man under 23 years old would actually take over the scepter passed down by Grothendick!"

Schultz stood up with some emotion and applauded. At the beginning, Pang Xuelin had tried to compete with him, to later admire him, and now, Pang Xuelin had become a towering mountain in his heart, and he could only look up.

...

On the other side of the auditorium.

Tan Hao clapped and stood up and said, "For our scientific community in China and the whole world, today is probably a historic day."

Sometimes, it may take decades or even hundreds of years to show results in the advancement of basic science.

But sometimes, on the day this theory is born, it will have a significant impact on the entire scientific community.

There is no doubt that the Ponzi geometric theory and the solution problems of systems of nonlinear partial differential equations belong to the latter.

Xu Xincheng and Liu Tingbo also stood up and looked at the figure on the stage, feeling a little moved.

Everyone understands what Tan Hao means.

With Pang Xuelin's current academic achievements, even if he does not have any heavyweight awards, it will not affect his academic status at all.

The applause lasted for a full five minutes before gradually stopping.

But everyone's eyes were still focused on Pang Xuelin.

Pang Xuelin smiled and said, "Thank you everyone. Next, if you have any questions during the solution process, you can raise your hand to ask questions at any time!"

Soon, in the hall, many people began to raise their hands in groups of three or three.

After all, there are still relatively limited mathematicians who can understand the entire process of Pang Xuelin's solution at the first time, and many mathematicians are still in a ignorant way.

"Okay, the gentleman sitting in the fourth row of the third row, do you have any questions?"

Soon, the staff at the conference venue handed the microphone to the other party.

The Latino scholar who looked over thirty years old and wearing glasses said: "Professor Pang, I am Garden Leslie, associate professor of computer science at Stanford University. I would like to ask..."

...

The next question session was calm.

With specific cases as reference, combined with Pang Xuelin's paper, most scholars present have already figured out how to solve nonlinear partial differential equation systems through Ponzi geometry.

When there is no problem with the overall solution idea, the rest are some minor problems.

Pang Xuelin patiently answered the questions of every questioner.

Time passed minute by minute, and before I knew it, fewer and fewer people asked questions.

"Okay, do you have any questions? If there is no problem, then this Ponzi Geometry Report Conference will end here. In addition, I will notify you that from next month, General Jiang will hold a Ponzi Geometry seminar. The seminar will be held in the form of a seminar. Participants must regularly report their research results and experiences on current cutting-edge research papers in the international mathematics community, and question and defend each other. The opening time is tentatively set for January next year, lasting for one year, and you can join and exit at any time. Later, General Jiang will publish the registration link for participating in the seminar on the official website. We will select 20 to 30 people from all applicants to participate in the seminar."

After Pang Xuelin finished speaking, the audience was immediately in an uproar.

Everyone understands what this seminar means.

With the development of Ponzi geometry, this new discipline will become a hot topic in the mathematics community in the next few decades.

Wang Yuexin stared at Pang Xuelin on the stage without blinking, and said, "Grigory, it's great. I originally wanted to apply to Jiangda to be a visiting scholar. With this seminar, there is no need to be so troublesome. I must participate in this seminar."

Perelman was slightly stunned and said in surprise: "Are you serious?"

Wang Yuexin nodded and said, "Yes, my prime time in my academic career has been spent on far Abel geometry. Now Professor Pang Xuelin has constructed a more magnificent Ponzi geometry theory based on this. For me, this is a brand new field. I believe that following Professor Pang can learn more!"

Perelman frowned and did not respond.

The potential of Ponzi geometry in solving nonlinear partial differential equations made him realize that if he wanted to prove the existence and smoothness of n-s equations, he had to rely on Ponzi geometry.

But he was a person who was used to being alone in the crowd. He could not make such a big decision to let him go to a research institution to study and study.
