Abstract

Stability for hereditary subalgebras of the crossed product C*-algebra associated to the horocycle flow on a compact quotient of SL(2,R) can be deduced by looking at the range of the unique dimension function. As a consequence, for every cocompact subgroup of SL(2,R), the C*-algebra associated to its action on R^2 \ {0} is stable. In this talk I will explain how this result can be deduced from the original dynamics.
