Continuous coexistency preservers on effect algebras

Michiya Mori, Peter Šemrl

Let $H$ be a finite-dimensional Hilbert space, $dim H \geq 2$ . We prove that every continuous coexistency preserving map on the effect algebra $E (H)$ is either a standard automorph…

On 2-local nonlinear surjective isometries on normed spaces and C $^{*}$ -algebras

Michiya Mori

We prove that, if the closed unit ball of a normed space $X$ has sufficiently many extreme points, then every mapping $Φ$ from $X$ into itself with the following property is affine…
