摘要:Mazur's sphere theorem shows that the unit spheres of $L_p$-spaces, $1\leq p<\infty$, are H\"{o}lder homeomorphic to the unit sphere of a Hilbert space with explicit H\"{o}lder estimates. In this talk, we introduce some related applications of the theorem in the nonlinear geometry of Banach spaces, coarse geometry and theoretical computer science. This is joint work with Bo Xiang.
