A **nonlinear eigenproblem** is a mathematical problem where one seeks to find scalars (eigenvalues) and corresponding non-zero vectors (eigenvectors) such that a nonlinear equation involving a nonlinear operator is satisfied. In contrast to the classical eigenvalue problem, where the operator is linear (i.e.
