I know the construction of 3D topological quantum field theory (TQFT) from a modular tensor category.
I heard that we can even (mathematically) construct 4D TQFT from a modular tensor category. I would like to know how to construct it.
I'd like to study it but I don't know how to search references. Is there any good word to search this 4D TQFT? Or could you suggest references?
I also want to know if there is another mathematically constructed 4D TQFT and how it is called.
Thank you in advance.
