Sobolev spaces on Lie manifolds and regularity for polyhedral domains
Bernd Ammann, Alexandru D. Ionescu, Victor Nistor
We study some basic analytic questions related to differential operators on Lie manifolds, which are manifolds whose large scale geometry can be described by a a Lie algebra of vec…
