A compact zero-dimensional space is called \(h\)-homogeneous if all nonempty clopen subsets are homeomorphic. Equivalently, \(X\) is the Stone space of a homogeneous Boolean algebra. Most topologically homogeneous zero-dimensional compact spaces are \(h\)-homogeneous, but not all. In this interesting paper, the authors show that the universal minimal flow of the homeomorphism group of an \(h\)-homogeneous compact space is the compact space of maximal chains of nonempty closed subsets of \(X\). This space was introduced by Uspenskij. Several known results are consequences of the main result in this paper.
