3-流形中曲面的Frobenius代数与skein模

Frobenius algebras and skein modules of surfaces in 3-manifolds

Uwe Kaiser

摘要:

对于每个Frobenius代数,定义了嵌入在给定的3-流形中的曲面的skein模,并在边界上限定了一个指定的曲线系统。绞关系是局部的,并产生相应的拓扑量子场论的某个自然扩张的核。特别是3-球的skein模同构于Frobenius代数的基环。我们证明了一个表示定理的绞链模块与发电机不可压缩曲面着色的Frobenius代数的生成集的元素,并与确定的管道几何关系的流形和关系的代数。

英文摘要:

For each Frobenius algebra there is defined a skein module of surfaces embedded in a given 3-manifold and bounding a prescribed curve system in the boundary. The skein relations are local and generate the kernel of a certain natural extension of the corresponding topological quantum field theory. In particular the skein module of the 3-ball is isomorphic to the ground ring of the Frobenius algebra. We prove a presentation theorem for the skein module with generators incompressible surfaces colored by elements of a generating set of the Frobenius algebra, and with relations determined by tubing geometry in the manifold and relations of the algebra.
