作为Frobenius对象的球体

Spheres as Frobenius objects

Djordje Baralic, Zoran Petric, Sonja Telebakovic

摘要:

按照通常分配给1维球体的Frobenius结构的模式,我们研究了所有其他维度球体的Frobenius结构。从维度$d=1$开始,所有的球面都是范畴中的交换Frobenius对象,其箭头是${(d+1)}$维配边。关于弗罗贝纽斯对象的语言,这些领域之间没有区别-它们都没有用这种语言制定的附加方程。相应的结构使0维球体不是可交换的,而是对称的弗罗贝纽斯对象。利用一维拓扑量子场论将该球面映射到矩阵Frobenius代数上,对应于Richard Brauer给出的一类图解代数的表示.

英文摘要:

Following the pattern of the Frobenius structure usually assigned to the 1-dimensional sphere, we investigate the Frobenius structures of spheres in all other dimensions. Starting from dimension $d=1$, all the spheres are commutative Frobenius objects in categories whose arrows are ${(d+1)}$-dimensional cobordisms. With respect to the language of Frobenius objects, there is no distinction between these spheres---they are all free of additional equations formulated in this language. The corresponding structure makes out of the 0-dimensional sphere not a commutative but a symmetric Frobenius object. This sphere is mapped to a matrix Frobenius algebra by a 1-dimensional topological quantum field theory, which corresponds to the representation of a class of diagrammatic algebras given by Richard Brauer.
