Daniel Graves

AI总结:

本文结合 PROPs、PROBs 与交叉单纯群理论,构造出编码等变幺半群结构的范畴,其代数范畴等价于带群作用的各类幺半群,并扩展至平衡辫张范畴和对合幺半群。

摘要:

等变幺半群是数学许多分支中非常重要的对象:它们结合了乘法的概念和群作用的概念。在本文中,我们将通过结合 PROPs 和 PROBs 理论与交叉单纯群理论,构造编码带有群作用的幺半群所承载结构的范畴。PROPs 和 PROBs 分别是用于编码对称幺半范畴和辫张范畴中对象所承载结构的范畴,而交叉单纯群是编码有单位元的、结合的乘法以及相容群作用的范畴。我们将利用对称和辫交叉单纯群的扩张,产生其代数范畴等价于带有群作用的幺半群、余幺半群和双幺半群范畴的 PROPs 和 PROBs。我们将使用带状辫交叉单纯群把该理论扩展到平衡辫张范畴。最后,我们将使用超八面体交叉单纯群来编码带有相容群作用的对合幺半群的结构。

英文摘要:

Equivariant monoids are very important objects in many branches of mathematics: they combine the notion of multiplication and the concept of a group action. In this paper we will construct categories which encode the structure borne by monoids with a group action by combining the theory of PROPs and PROBs with the theory of crossed simplicial groups. PROPs and PROBs are categories used to encode structures borne by objects in symmetric and braided monoidal categories respectively, whilst crossed simplicial groups are categories which encode a unital, associative multiplication and a compatible group action. We will produce PROPs and PROBs whose categories of algebras are equivalent to the categories of monoids, comonoids and bimonoids with group action using extensions of the symmetric and braid crossed simplicial groups. We will extend this theory to balanced braided monoidal categories using the ribbon braid crossed simplicial group. Finally, we will use the hyperoctahedral crossed simplicial group to encode the structure of an involutive monoid with a compatible group action.
