Interpolation estimates for entropy numbers with applications to non-convex bodies Original Research Article

We complement classical results on the interpolation of entropy numbers as well as certain ss-numbers and present an application to a class of non-convex bodies which are generalizations of pp-convex bodies. In particular we apply the estimates of entropy numbers of operators on Calderón–Lozanovskii spaces to approximation of the volume of φφ-absolute convex hull of nn points in RkRk generated by a class of concave functions.
