ABSTRACT: | I will survey some classical and recent ideas in higher-dimensional arithmetic geometry. About the speaker: Yuri Tschinkel received his doctorate in mathematics from the Massachusetts Institute of Technology in 1992. From 1992-95 he was Junior Fellow of the Harvard Society of Fellows, and from 1995-96 he was a Leibniz fellow at the Ecole Normale Superieure in Paris. Yuri Tschinkel was a faculty member at the University of Illinois at Chicago, a visiting associate professor at Princeton University, the Gauss chair of mathematics at the University of Gottingen, and professor and chair of the mathematics department at the Courant Institute, New York University. He was also a member of the Institute for Advanced Study in Princeton and held visiting fellowships at the Isaac Newton Institute for Mathematical Sciences in Cambridge, University of Tokyo, Max Planck Institute in Bonn, Institut des Hautes Etudes Scientifiques in Paris, Eidgenossische Technische Hochschule Zurich, and Research Institute for Mathematical Sciences at Kyoto University. He was an invited speaker at the International Congress of Mathematicians in Madrid in 2006. He serves on the editorial boards of Algebraic Geometry, Experimental Mathematics, the Bulletin of the American Mathematical Society, the European Journal of Mathematics, and the Progress in Mathematics series from Birkhauser. He is a member of the Scientific Council of the Fondation Sciences Mathematiques de Paris and has served on several other advisory boards. Tschinkel's research is at the interface of algebraic geometry and number theory. He studies higher-dimensional algebraic varieties, their hidden symmetries and rational points. He is the author of 100 papers and editor of 14 books. |
