Combinatorial quantization of 4d 2-Chern-Simons theory I: the Hopf category of higher-graph states
Hank Chen
2-Chern-Simons theory, or more commonly known as 4d BF-BB theory with gauged shift symmetry, is a natural generalization of Chern-Simons theory to 4-dimensional manifolds. It is pa…

Combinatorial quantization of 4d 2-Chern-Simons theory II: Quantum invariants of higher ribbons in
Hank Chen
This is a continuation of the first paper (arXiv:2501.06486) of this series, where the framework for the combinatorial quantization of the 4d 2-Chern-Simons theory with an underlyi…

Categorical quantum symmetries and ribbon tensor 2-categories
Hank Chen
In a companion work on the combinatorial quantization of 4d 2-Chern-Simons theory, the author has constructed the Hopf category of quantum 2-gauge transformations $\tilde{C}=\mathb…
