In recent times, tensor product of rings has become increasingly relevant in various contexts. Tensorproduct of algebras - Wikipedia. In mathematics, the tensor product of two algebras over a commutative ring R is also an R -algebra. This gives the tensor product of algebras.
When the ring is a field, the most common application of such products is to describe the product of algebra representations. Definition of tensor product of rings - Mathematics Stack Exchange. To gain full voting privileges, Let X= SpecA,Y= SpecB X = Spec A, Y = Spec B and Z = SpecC Z = Spec C be affine schemes, with A,B,C A, B, C commutative rings.
According to Wikipedia, the following holds: X×Y Z ≅ Spec(A⊗BC) X × Y Z ≅ Spec (A ⊗ B C).
