Model spaces in sub-Riemannian geometry
Erlend Grong
We consider sub-Riemannian spaces admitting an isometry group that is maximal in the sense that any linear isometry between the horizontal tangent spaces is realized by a global is…

Stochastic completeness and gradient representations for sub-Riemannian manifolds
Erlend Grong, Anton Thalmaier
Given a second order partial differential operator satisfying the strong Hörmander condition with corresponding heat semigroup , we give two different stochastic represent…
