MATHEMATICAL SCIENCES: ELLIPTIC THREEFOLDS AND CALABI-YAU THREEFOLDS

9400873格罗斯教授将研究椭圆三折和Calabi-Yau三折。特别是，他将研究Calabi-Yau三重变形类，以期获得分类定理。他还打算进一步研究最近发现的镜面对称现象。这是代数几何领域的研究，但它与本世纪理论物理的两大进步--量子力学和广义相对论--直接相关。代数几何本身是现代数学中最古老的部分之一，但在过去的25年里，它已经取得了革命性的成就。在它的起源中，它处理的是可以在平面上用最简单的方程定义的图形，即多项式。如今，该领域不仅使用代数的方法，而且使用分析和拓扑学的方法，反过来，在这些领域以及物理、理论计算机科学和机器人中也找到了应用。

9400873 Gross Professor Gross will study elliptic threefolds and Calabi-Yau threefolds. In particular he will study deformation classes of Calabi-Yau threefolds with a view to obtaining classification theorems. He also intends to further study the recently discovered phenomenon of mirror symmetry. This is research in the field of algebraic geometry, yet it directly connects to two of the great advances in theoretical physics in this century--quantum mechanics and general relativity. Algebraic geometry itself is one of the oldest parts of modern mathematics, but one which has had a revolutionary flowering in the past quarter-century. In its origin, it treated figures that could be defined in the plane by the simplest equations, namely polynomials. Nowadays the field makes use of methods not only from algebra, but from analysis and topology, and conversely is finding application in those fields as well as in physics, theoretical computer science, and robotics.
