Abstract

Inspired by an LpL_p Steiner formula for the LpL_p affine surface area proved by Tatarko and Werner, we define, in analogy to the classical Steiner formula, LpL_p-Steiner quermassintegrals. Special cases include the classical mixed volumes, the dual mixed volumes, the LpL_p affine surface areas and the mixed LpL_p affine surface areas. We investigate the properties of the LpL_p-Steiner quermassintegrals in a special class of convex bodies. In particular, we show that they are rotation and reflection invariant valuations in this class of convex bodies with a certain degree of homogeneity. Such valuations seem new and have not been observed before.
