报告摘要：The famous affine Bernstein theorem, also called Chern’s conjecture, asserts that an affine maximal graph of a smooth, locally uniformly convex function on Euclidean space is a paraboloid. This conjecture was first proved by Trudinger-Wang in dimension two in 2000. One can easily find affine maximal graphs which are not paraboloid on half spaces. In this talk, we show a Liouville theorem for the affine maximal equation on half-spaces with certain assumptions. The proof is based on the study on the related linearized Monge-Amp\`ere equation and the Monge-Amp\`ere equation
