ABSTRACT: By a manifold with geometric singularities we understand a stratified space M that has a specific structure close to the singular subset M', for instance, of conical, edge, or corner type, modelled on degenerate Riemannian metrics. A special case is manifolds with smooth boundary. In our talk we discuss ellipticity in algebras of (pseudo-) differential operators on such spaces, based on principal symbolic hierarchies, and aspects of the index theory.
