Excision for Spaces of Admissible Skeins
Ingo Runkel, Christoph Schweigert, Ying Hong Tham
The skein module for a d-dimensional manifold is a vector space spanned by embedded framed graphs decorated by a category A with suitable extra structure depending on the dimension…
The Y-Product
Alice Kwon, Ying Hong Tham
We present a topological construction that provides many examples of non-commutative Frobenius algebras that generalizes the well-known pair-of-pants. When applied to the solid tor…
Explicit Factorization of a Categorical Center
Jin-Cheng Guu, Ying Hong Tham
Given a braided fusion category , it is well known that the natural map from the square of to the (Drinfeld) categorical center is an e…
On the Category of Boundary Values in the Extended Crane-Yetter TQFT
Ying Hong Tham
The Crane-Yetter state sum is an invariant of closed 4-manifolds, defined in terms of a triangulation, based on 15-j symbols associated to the category A of representations over qu…
Reduced Tensor Product on the Drinfeld Center
Ying Hong Tham
The annulus comes with a "stacking" operation which glues two annuli into one. This provides a tensor product structure on the category of boundary values $Z_{\text{CY}}(\text{Ann}…
Factorization Homology and 4D TQFT
Alexander Kirillov, Ying Hong Tham
In [BK], it is shown that the Turaev-Viro invariants defined for a spherical fusion category extends to invariants of 3-manifolds with corners. In [Kir], an equivalen…
The Elliptic Drinfeld Center of a Premodular Category
Ying Hong Tham
Given a tensor category C, one constructs its Drinfeld center Z(C) which is a braided tensor category, having as objects pairs (X, lambda), where X in Obj(C) and lambda is a half-b…
