Abstract
We study the extension of isometries between the unit spheres of quasi-Banach spaces L p for 0 < p < 1. We give some sufficient conditions such that an isometric mapping from the the unit sphere of L p(µ) into that of another L p(.) can be extended to be a linear isometry defined on the whole space.
