Given a matrix-valued function F that depend nonlinearly on a single
parameter z, the basic nonlinear eigenvalue problem consists of finding complex scalars z for which F(z) is singular. Such problems arise in many areas of computational science and engineering, including acoustics, control theory, fluid mechanics and structural engineering.

In this talk we will discuss some interesting mathematical properties of
nonlinear eigenvalue problems and then present recently developed
algorithms for their numerical solution. Emphasis will be given to the linear algebra problems to be solved.
