Abstract
It is known that a matrix polynomial with unitary matrix coefficients has its eigenvalues in the annular region . We prove in this short note that under certain assumptions, matrix polynomials with either doubly stochastic matrix coefficients or Schur stable matrix coefficients also have eigenvalues in similar annular regions.
