Tensor product
In mathematics, the tensor product
V
⊗
W
{\displaystyle V\otimes W}
of two vector spaces V and W (over the same field) is a vector space to which is associated a bilinear map
V
×
W
→
V
⊗
W
{\displaystyle V\times W\rightarrow V\otimes W}
that maps a pair
(
v
,
w
)
,
 
v
∈
V
,
w
∈
W
{\displaystyle (v,w),\ v\in V,w\in W}
to an element of
V
⊗
W
{\displaystyle V\otimes W}
denoted
v
⊗
w
{\displaystyle v\otimes w}
.
