与例外完整性有关的七、四、三维边值问题

Boundary value problems in dimensions seven, four and three related to exceptional holonomy

Simon Donaldson

摘要:

本文在7-带边流形流形上引入了一个G_{2}结构的边值问题,边界上具有给定的3-形式.我们对这个问题做了一些一般性的观察,然后通过施加对称性来更详细地研究4维和3维的减少。三维约化允许一个对偶变分形式的真正的Monge-Ampere方程的解

英文摘要:

In the paper we introduce a boundary value problem for a G_{2} structure on a 7-manifold with boundary, with prescribed 3-form on the boundary. We make some general observations about this problem and then study in more detail reductions to 4 and 3 dimensions by imposing symmetry. The 3-dimensional reduction admits a dual variational formulation in terms of solutions of the real Monge-Ampere equation
