This awards supports the research of Professor V. Shokurov to work in algebraic geometry. He will work on problems involved in minimal model theory in dimensions greater than or equal to 3. He hopes to show that flips exist in dimension n whenever the Log Minimal Model program holds in dimension n-1. He will also study log canonical singularities in dimension 3. The research is in the field of algebraic geometry, one of the oldest parts of modern mathematics, but one which blossomed to the point where it has, in the past 10 years, solved problems that have stood for centuries. Originally, it treated figures defined in the plane by the simplest of equations, namely polynomials. Today, the field uses methods not only from algebra, but also from analysis and topology, and conversely it is extensively used in those fields. Moreover it has proved itself useful in fields as diverse as physics, theoretical computer science, cryptography, coding theory and robotics.

该奖项支持V. Shokurov教授在代数几何方面的研究。他将研究维度大于或等于3的最小模型理论中的问题。他希望证明，只要对数极小模型程序在n-1维中成立，那么在n维中就存在翻转。他还将研究3维的对数正则奇点。这项研究是在代数几何领域进行的，代数几何是现代数学中最古老的部分之一，但在过去的10年里，它已经发展到解决了几个世纪以来一直存在的问题的程度。最初，它用最简单的方程，即多项式来处理平面上定义的图形。今天，该领域不仅使用代数的方法，而且还使用分析和拓扑的方法，相反，它在这些领域中被广泛使用。此外，它已被证明在物理学、理论计算机科学、密码学、编码理论和机器人等多种领域都很有用。
