*讲座内容简介：
The study of fully nonlinear PDEs of second order originated from Weyl and Minkowski problems in classical geometry, and Calabi conjectures in Kahler geometry. Since the breakthroughs in the 70-80's of last century, it has developed into an active research field in mathematics. In this talk we shall present some of the geometric problems and related fully nonlinear PDEs. At the second half of the talk we shall discuss the classical solvability of a general class of fully nonlinear equations on manifolds, and report some recent results if time permits.
