Classification of horospherical invariant measures in higher rank: Teaser

Abstract

This is an expository/teaser version of [arXiv:2601.22668] for a very special case of products of $\mathrm{CAT}(-1)$ spaces. We keep this on arXiv as many parts of the argument of [arXiv:2601.22668] are simplified in this special case.
