Compactification Lattices of Subsemigroups of Sl(2, R)
by
Wolfgang A.F. Ruppert
University for Bodenkultur
Coauthors: Brigitte Breckner

This talk presents recent results about the structure of topological semigroup compactifications of closed connected submonoids with dense interior of Sl(2, R). For a large class of such semigroups explicit constructions yielding all possible topological semigroup compactifications are given and the structure of the compactification lattice is determined.
