Cup product

In mathematics, specifically in algebraic topology, the cup product is a method of adjoining two cocycles of degree p and q to form a composite cocycle of degree p + q. In de Rham cohomology, the cup product is also known as the wedge product and in this sense is a special case of Grassmann's exterior product.
