✦ Synopsis


In this paper certain operator ideals are used to study interpolation orbit functors. It is shown that orbit functors from the couples of weighted p or c 0 spaces coincide on the class of regular finite dimensional couples with coorbit interpolation functors generated by certain operator ideals. As an application the reiteration theorems for interpolation orbits spaces in the dual couples of compatible Banach spaces satisfying certain approximation property are proved.

Sharp reiteration theorems for the K-interpolation method in limiting cases are proved using two-sided estimates of the K-functional. As an application, sharp mapping properties of the Riesz potential are derived in a limiting case.
