# Definition of a Differential Eigenvalue Problem?

## Homework Statement

I would like to know what the definition of a Differential Eigenvalue Problem is please?

## Homework Equations

\lambda y = L y, where \lambda is eigenvalue, L is a linear operator.

## The Attempt at a Solution

I have searched via google, encylopedia britanica, wikipedia but only have a vague understanding. If someone could help me define it that would be great.

Thank you.
