Abstract: In this talk, we develop systematically the pointwise regularity for viscosity solutions of fully nonlinear elliptic equations in general forms. In particular, the equations with quadratic growth (called natural growth) in the gradient are covered. We obtain a series of interior pointwise $C^{k,\alpha}$ regularity ($k\geq 1$ and $0<\alpha<1$). Some regularity results are new even for the linear equations. Moreover, the minimum requirements are imposed to obtain above regularity and our proofs are simple.
Speaker: Yuanyuan Lian is currently a postdoc at Shanghai Jiao Tong University. Her research focuses on the regularity of PDE. She has published 6 mathematical papers (in J. Math. Pures Appl.，J. Differential Equations and Israel J. Math. etc.) and 5 material science papers (in J. Alloys Compd. and J. Cryst. Growth ets.). In addition, she has obtained 5 national invention patents and a Postdoctoral Fund.
