Retraction methods and fixed point free maps with null minimal displacements on unit balls

C. S. Barroso, V. Ferreira

In this paper we consider the class of Lipschitz maps on the unit ball $B_X$ of a Banach space $X$, and the question we deal with is whether for any $\hat{I}»>1$ there exists a $\hat{I}»$-Lips…
