Phase-isometries on the unit sphere of $C (K)$

Dongni Tan, Yueli Gao

We say that a map $T : S_{X} \to S_{Y}$ between the unit spheres of two real normed-spaces $X$ and $Y$ is a phase-isometry if it satisfies \begin{eqnarray*} \{\|T(x)+T(y)\|, \|T(…

A property in vector-valued function spaces

Kexin Zhao, Dongni Tan

This paper deals with a property which is equivalent to generalised-lushness for separable spaces. It thus may be seemed as a geometrical property of a Banach space which ensures t…
