2-local standard isometries on vector-valued Lipschitz function spaces

Abstract

Under the right conditions on a compact metric space $X$ and on a Banach space $E$, we give a description of the $2$-local (standard) isometries on the Banach space $Lip(X,E)$ of vector-valued Lipschitz functions from $X$ to $E$ in terms of a generalized composition operator, and we study when every $2$-local (standard) isometry on $Lip(X,E)$ is both linear and surjective.
