报告摘要 Abstract:
In this talk, we will review the classical Gehring’s linked sphere problem. Gage’s solution to this problem will be sketched. We will also discuss Gromov’s point of view of this problem and his approach to the isoperimetric inequality in an infinite dimensional Banach space. Our spherical version of this linked sphere problem will also be mentioned.
