Khovanov同调与规范理论

Khovanov Homology And Gauge Theory

Edward Witten

摘要:

在这些说明中,我将勾勒一个新的方法Khovanov同源的结和链接的基础上计数的解决方案,某些椭圆偏微分方程在四,五个层面。这些方程是在四维和五维流形上用一个相当微妙的边界条件来编码节点和链接。该结构在形式上类似于Floer和Donaldson理论的三维和四维。它是用量子场论论证发现的,但可以用经典规范理论来描述和理解。(基于2011年6月加州大学伯克利分校低维流形和高维范畴会议上的演讲)。

英文摘要:

In these notes, I will sketch a new approach to Khovanov homology of knots and links based on counting the solutions of certain elliptic partial differential equations in four and five dimensions. The equations are formulated on four and five-dimensional manifolds with boundary, with a rather subtle boundary condition that encodes the knots and links. The construction is formally analogous to Floer and Donaldson theory in three and four dimensions. It was discovered using quantum field theory arguments but can be described and understood purely in terms of classical gauge theory. (Based on a lecture at the conference Low-Dimensional Manifolds and High-Dimensional Categories, University of California at Berkeley, June 2011).
