Mathematical Sciences: Linear Systems on Higher Dimensional Varieties

点击翻译按钮获取中文摘要

This awards supports the research of Professor L. Ein to work in algebraic geometry. He will work on linear systems on higher dimensional varieties. He will try to find optimal criteria for freeness and very ampleness for adjoint linear series on threefolds. He will also study syzygies of adjoint linear series. 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.
