The School of Sciences couldn't find a topology expert, and even the familiar Edward Witten couldn't be trusted.
Zhao Yi had no choice but to seek external help.
The domestic academic circle, especially the mathematics circle, is not large. He asked Zhou Li and was introduced to a reliable person, Professor Zhou Youjin from Shuimu University.
In the domestic mathematics circle, Zhou Youjin was not very famous, probably because he had only a few achievements, and they were all in 'domestic obscure subjects.'
In fact, Zhou Youjin is very outstanding. His research on topological space structure was published in the four major mathematical journals, including the most difficult "Acta Mathematica". Shuimu University officially congratulated him when his research was published. However, because topology is too obscure in the domestic mathematics circle, once it passes, it passes.
