Generalized Maximum Principles and Stochastic Completeness for Pseudo-Hermitian Manifolds
- MathematicsChinese Annals of Mathematics, Series B
- 2022
In this paper, the authors establish a generalized maximum principle for pseudo-Hermitian manifolds. As corollaries, Omori-Yau type maximum principles for pseudo-Hermitian manifolds are deduced.…
