Abstract:

In this paper, we study the extension of isometries between unit spheres of atomic $AL_p$-spaces $(0<p<\infty ,\ p\neq 2)$. We find a condition under which an isometry $T$ between unit spheres can be linearly isometrically extended. Moreover, we prove that every onto isometry between unit spheres of atomic $AL_p$-spaces $(0<p<\infty ,\ p\neq 2)$ can be linearly isometrically extended to the whole space.
