摘要:In this talk, we will introduced some Liouville-type theorems for semi-linear differential equations/inequalities with respect to the sub-Laplacian on sub-Riemannian manifolds with a generalized curvature-dimension condition, including elliptic, parabolic and hyperbolic cases. The main technical tool is to construct some cut-off functions with controlled second-order derivatives. This is a joint work with Bing Wang.
