Idea

A tensor category is a category equipped with an operation similar to the tensor product in Ab.

The precise definition associated with the term “tensor category” varies somewhat in the literatur.

It may mean: * any monoidal category, * specifically a symmetric monoidal category (and then a quasitensor category is a braided monoidal category), * an additive (symmetric) monoidal category, * an Ab-enriched or Vect-enriched (symmetric) monoidal category.
