[Banach] Abstract of a paper by Eva Pernecka

This is an announcement for the paper "On uniformly differentiable mappings" by Eva Pernecka.

Abstract: We are concerned with the rigidity of $\ell_\infty$ and $\ell_\infty^n$ with respect to uniformly differentiable mappings. Our main result is a non-linear analogy of the classical result on the rigidity of $\ell_\infty$ with respect to non-weakly compact linear operators by Rosenthal, and it generalises the theorem on the non-complementability of $c_0$ in $\ell_\infty$ due to Phillips.
