Visiting Harvard

Lu Zhou remembered that Qiu Chengtong was the leading person in partial differential equations.

There was no doubt about Old Qiu's achievements in differential geometry.

Anyone who had read the book "Differential Geometry" would know that he was the founder of geometric analysis.

What was the geometric analysis?

It was the study of integrating partial differentiation into differential geometry.

Although the Chinese academic community had mixed opinions on this figure, the international academic community still respected this scholar.

This could be seen from his rewards.

There were only two mathematicians who had won the three big prizes: the Wolf Prize, the Fields Medal, and the Crafoord Prize. One of them was Lu Zhou's mentor, Deligne, and the other was Qiu Chengtong.
