Algebraic version of a 2-dimensional TQFT

Graphical identities of Frobenius algebras

Frobenius algebras encapture the algebraic content of a 2-dimensional TQFT (topological quantum field theory). These algebras are equipped with a non-degenerate bilinear form (a “trace”) which allows for constructing cups and caps.
