摘要:The non-integer matrix (NIM) solutions of matrix equations are closely related to the NIM representations over fusion rings and the module categories over tensor categories. In this talk we shall introduce a general theory of irreducible NIM representation over fusion ring. We give the minimum upper bound of rank of NIM representation and the general classification methods of irreducible ...
Abstract：The first part of the talk will be about a new and simplified presentation of the classical pure braid group. Motivated by twist functors from Algebraic geometry, the generators are given by the squares of longest elements over connected subgraphs, and the relations are either commutators or certain length 5 palindromic relations.In the second part of the talk, I will summarise a cons...
