摘要:In this talk, we will present fundamental $C^{1}$ estimate for solutions to $\Delta_{b}u=0$ and $C^{0}$ and $C^{1}$ estimates for solutions to a class of nonlinear elliptic equations of the form $\Delta_{b}u+au\ln u+bu=0$ on pseudohermitian manifold. The proof consists of combining the Nash-Moser iteration and Saloff-Coste type sobolev inequalities. This talk is based on joint work with Dr. Shitong Niu.
