External Composition Law

Consider two sets E and Ω. The application of Ω × E on E is called an external composition law on E. The elements of Ω are called the operators.
As indicated in the definition, the results of this composition law are elements of E.

Example

The multiplication of a vector by a scalar (real number) is an external composition law whose results are vectors.
