摘要：In this talk, I mainly discuss an improved and easy-to-followed new proof of the convexity estimates of level sets of minimal graphs, which greatly simplifies the previous proof. I also mention some results on harmonic functions.

简介：Wei Zhang is an associate professor at School of Mathematics and Statistics of Lanzhou University. He received his Ph.D. degree from University of Science and Technology of China in 2011. His main research interest is in convexity issue and regularity theory of nonlinear elliptic PDEs. Part of his recent works were published on the journal Calc. Var. PDE, J. Differential Equations, Proc. Amer. Math. Soc., etc.
