Abstract
We characterize those positive functions which are invariant for a bounded kernel, and which have a Choquet-type integral representation. Such a repre sentation relies on the wellknown Choquet-type integral representation of m easures which are invariant for a kernel. We apply our results to convoluti on kernels with spread-out measures on second countable locally compact Abe lian groups.
