Holomorphic extensions of highest weight representations to Olshanskii semigroups


[ Abstract ]
In this lecture I will present a proof of Olshanskii's Theorem, which says that
for a simple group of Hermitean type unitarizable highest weight
representations can be holomorphically extended to contractive representations
of a complex semigroup containing the group in its boundary.
