Surjective isometries on function spaces with derivatives

Abstract

Let AA be a complex Banach space with a norm f=fX+d(f)Y\|f\|=\|f\|_X+\|d(f)\|_Y for fAf\in A, where dd is a complex linear map from AA onto a Banach space BB, and K\|\cdot\|_K represents the supremum norm on a compact Hausdorff space KK. In this paper, we characterize surjective isometries on (A,)(A,\|\cdot\|), which may be nonlinear. This unifies former results on surjective isometries between specific function spaces.
