Abstract

We discuss matrix polynomials expressed in a Bernstein basis, and the associated polynomial eigenvalue problems. Using Mobius transformations of matrix polynomials, large new families of strong linearizations are generated. We also investigate matrix polynomials that are structured with respect to a Bernstein basis, together with their associated spectral symmetries. The results in this paper apply equally well to scalar polynomials, and include the development of new companion pencils for polynomials expressed in a Bernstein basis.
