A Haskell library for stringnet calculations
The executable currently computes the representation of a braid generator in the Turaev-Viro-Barrett-Westbury TQFT representation in terms of the structural morphisms of an arbitrary spherical fusion category.
- Clone the repository
- Install stack
- Run the following commands from the stringnet base directory:
stack unpack matrix-0.3.5.0 stack setup stack build stack exec stringnet
