On Birkhoff-James orthogonality preservers between real non-isometric Banach spaces

Ryotaro Tanaka

Real smooth three-dimensional or higher Banach spaces are isomorphic with respect to the nonlinear structure of Birkhoff-James orthogonality if and only if they are isometrically i…

A solution to Tingley's problem for isometries between the unit spheres of compact C $^{}$ -algebras and JB $^{}$ -triples

Antonio M. Peralta, Ryotaro Tanaka

Let $f : S (E) \to S (B)$ be a surjective isometry between the unit spheres of two weakly compact JB $^{*}$ -triples not containing direct summands of rank smaller than or equal to 3. Sup…
