Integrate on a closed stratified surface
Xiao-Xue Wei
We prove that the Drinfeld center centralized by a symmetric fusion category is a symmetric monoidal functor if we choose proper domain and codomain categories. We also compute the…
Algebras over a symmetric fusion category and integrations
Xiao-Xue Wei
We study the symmetric monoidal 2-category of finite semisimple module categories over a symmetric fusion category. In particular, we study -algebras in this 2-category and co…
Parametric Euler Sums of Harmonic Numbers
Junjie Quan, Xiyu Wang, Xiaoxue Wei +1
We define a parametric variant of generalized Euler sums and construct contour integration to give some explicit evaluations of these parametric Euler sums. In particular, we estab…
Cochains in 2-TQFT
Xiaoxue Wei
John C.Baez reinterpreted 2-dimensional and 3-dimensional topological quantum field theories (abbreviated as 2-TQFT and 3-TQFT) in "A prehistory of n-categorical physics"[JC11]. In…
