主讲内容:
In this talk, we introduce the second order derivative estimates for Hessian equations $\sigma_k(u_{ij}+u\delta_{ij})=f(x, u, \nabla u)$ on $\mathbb{S}^n$, which can be regarded as an generalization of Christoffel-Minkowski type problems. Furthermore, we derive the existence and uniqueness results for convex solution of general Christoffel-Minkowski problem $\sigma_k(u_{ij}+u\delta_{ij})=\varphi(x)g(u)$ based on the a priori estimates and constant rank theorem.
