论文摘要
尽管较高的捆绑包与较高的量规理论显然相关,但除了阿贝尔束外壳以外的例子很难遇到。人们特别喜欢看到2个捆绑包,其中结构2组是与紧凑的简单简单连接的谎言组关联的字符串2组。这次演讲将概述一种在同质空间上构建许多示例的方法。我们还将详细考虑一个例子,为局部琐碎化产生的交叉模块值的Cech Cocycle提供明确的公式。
While higher bundles are of clear relevance to higher gauge theory, examples other than abelian bundle gerbes are hard to come across. One would in particular like to see 2-bundles where the structure 2-group is the String 2-group associated to a compact simple simply-connected Lie group. This talk will outline a method to construct many examples over homogeneous spaces. We shall also consider one example in detail, giving explicit formulas for the crossed-module-valued Cech cocycle arising from a local trivialisation.
