2021-2-21 · In its original sense a tensor product is a representing object for a suitable sort of bilinear map and multilinear map. The most classical versions are for vector spaces (modules over a field) more generally modules over a ring and even more generally algebras over a commutative monad. In modern language this takes place in a multicategory.
