报告人简介:

        许瑞伟,河南师范大学副教授。曾到德国柏林工业大学、美国华盛顿大学、日本福冈大学进行学术访问。先后主持国家自然科学基金的天元基金、青年基金和面上项目。在Calc. Var.PDE., Ann. Global Anal Geom., Manuscripta Math.等国际知名杂志发表文章,在世界科学出版社合作出版专著《Affine Bernstein problems and Monge-Ampère equations》。

摘      要:

       In this talk, I shall show some classifications of Calabi hypersurfaces with parallelTchebychev vector field; and classifiction of Calabi hypersurfaces with parallel Fubini-Pick form. These hypersurfaces are all affine extremal hypersurfaces in Calabi geometry. In particular, we found many new Calabi complete and Euclidean complete affine extremal hypersurfaces, which are solutions of the fourth order PDE. These are joint work with Prof. Xing-xiao Li and Miaoxin Lei.
