Abstract
In this article, a classification of continuous, linearly intertwining, symmetric -Blaschke () valuations is established as an extension of Haberl's work on Blaschke valuations. More precisely, we show that for dimensions , the only continuous, linearly intertwining, normalized symmetric -Blaschke valuation is the normalized -curvature image operator, while for dimension , a rotated normalized -curvature image operator is an only additional one. One of the advantages of our approach is that we deal with normalized symmetric -Blaschke valuations, which makes it possible to handle the case . The cases where are also discussed by studying the relations between symmetric -Blaschke valuations and normalized ones.
