Given a linear endomorphism, an eigenvector of it is a vector which is taken by the linear map to a multiple of itself. This multiple is called the eigenvalue of the eigenvector.
It is sometimes required that an eigenvector is not the zero vector.
If the linear map acts as a differential operator on a space of functions, its eigenvectors are sometimes called eigenfunctions.
