Session 4. Banach Spaces and Operator Theory with Applications

Nonlinear versions of the Daugavet property

Dirk Werner, Freie Universität Berlin, Germany
A Banach space \(X\) has the Daugavet property if \begin{equation}\label{werner-01} \|\operatorname{Id}+T\|=1+\|T\| \end{equation} for all compact linear operators \(T\colon X\to X\). Classical examples include \(C[0,1]\), \(L_1[0,1]\) and the disc algebra. We shall discuss the validity of (1) in the setting of bilinear operators and Lipschitz operators.
