A circled multiplication cross joining two structures.
Also known as: Circled times, Tensor product, Otimes, Kronecker product sign
The circled cross denotes the tensor product, which combines two spaces into one whose dimension is the product rather than the sum of theirs. That difference from the direct sum is the fact that makes the two circled operators worth telling apart.
Denotes the tensor product of two vector spaces, modules or algebras.
Contexts: Mathematics
Produces a space whose dimension is the product of the two dimensions, where the direct sum gives their sum.

A slanted cross of two equal strokes drawn inside a circle that just contains it.
Circled plus adds dimensions; circled times multiplies them.
