Daugavet centers are separably determined
A linear bounded operator $G$ acting from a~Banach space $X$ intoa~Banach space $Y$ is a~Daugavet center if every linear boundedrank-$1$ operator $Tcolon X o Y$ fulfills$|G+T|=|G|+|T|$. We prove that $G colon X o Y$is a~Daugavet center if and only if for every separable subspaces$X_1subset X$ and...
