Title: Differential operators undergoing adiabatic transitions

Abstract: I will describe a geometric type of degeneration of differential operators, which includes semiclassical and adiabatic limits. The most basic result for elliptic operators of this type is the inheritance of invertibility from the limiting operators. I will discuss this and applications of it, in particular in differential topology.
