An optimal extension of Perelman's comparison theorem for quadrangles and its applications

Jianguo Cao, Bo Dai, Jiaqiang Mei

In this paper we discuss an extension of Perelman's comparison for quadrangles. Among applications of this new comparison theorem, we study the equidistance evolution of hypersurfa…

An extension of Perelman's soul theorem for singular spaces

Jianguo Cao, Bo Dai, Jiaqiang Mei

In this paper, we study open complete metric spaces with non-negative curvature. Among other things, we establish an extension of Perelman's soul theorem for possibly singular spac…
