Editing Glossary of tensor theory (section)

==Abstract algebra==
;[[Tensor product of fields]]
:This is an operation on fields, that does not always produce a field.

;[[Tensor product of R-algebras]]

;[[Clifford module]]
:A representation of a Clifford algebra which gives a realisation of a Clifford algebra as a matrix algebra.

;[[Tor functor]]s
:These are the [[derived functor]]s of the tensor product, and feature strongly in [[homological algebra]]. The name comes from the [[torsion subgroup]] in [[abelian group]] theory.

;[[Symbolic method of invariant theory]]

;[[Derived category]]

;[[Grothendieck's six operations]]
:These are ''highly'' abstract approaches used in some parts of geometry.
