Von Neumann algebras | Operator theory
In mathematics, and more specifically in the theory of von Neumann algebras, a crossed productis a basic method of constructing a new von Neumann algebra from a von Neumann algebra acted on by a group. It is related to the semidirect product construction for groups. (Roughly speaking, crossed product is the expected structure for a group ring of a semidirect product group. Therefore crossed products have a ring theory aspect also. This article concentrates on an important case, where they appear in functional analysis.) (Wikipedia).
The vector cross-product is another form of vector multiplication and results in another vector. In this tutorial I show you a simple way of calculating the cross product of two vectors.

Defining the Cross Product from Scratch
The cross product takes in two vectors and returns a vector orthogonal, or perpendicular, to both of them. Such a clean and simple property, however, is usually mired in its daunting formula. In this video, I show how one might think to define an operation that would return a vector orthog

Vector multiplication can be tricky, and in fact there are two kinds of vector products. We already learned the dot product, which is a scalar, but there is another way to multiply vectors to get another vector, and it's called the cross product. Let's learn how to do this now! Watch the
