[Banach] Abstract of a paper by Marek Balcerzak, Adam Majchrzycki, and Filip Strobin

This is an announcement for the paper "Uniform openness of multiplication in Banach spaces $L _p$" by Marek Balcerzak, Adam Majchrzycki, and Filip Strobin.

Abstract: We show that multiplication from $L_p\times L_q$ to $L_1$ (for $p,q\in [1,\infty]$, $1/p+1/q=1$) is a uniformly open mapping. We also prove the uniform openness of the multiplication from $\ell_1\times c_0$ to $\ell_1$. This strengthens the former results obtained by M. Balcerzak, A.~Majchrzycki and A. Wachowicz.
