AB - For the scalar holomorphic discrete series representations of ${\rm SU}(2,2)$ and their analytic continuations, we study the spectrum of a non-compact real form of the maximal compact subgroup inside ${\rm SU}(2,2)$. We construct a Cayley transform between the Ol’shanskiĭ semigroup having ${\rm U}(1,1)$ as Šilov boundary and an open dense subdomain of the Hermitian symmetric space for ${\rm SU}(2,2)$. This allows calculating the composition series in terms of harmonic analysis on ${\rm U}(1,1)$. In particular we show that the Ol’shanskiĭ Hardy space for ${\rm U}(1,1)$ is different from the classical Hardy space for ${\rm U}(2)$; this provides a counterexample to a statement in a paper by Gindikin.
