| Abstract: | A computation theory for solvents of nonmonic matrix polynomials is developed.A survey of the spectral theory of the associated lambda matrix in terms of the concept of eigenpair is done.The Unearization in a companion form is studied,and a generalization of the Vandermonde matrix is introduced.Conditions for the existence of solvents are given,and the estimation of their number is obtained.A numerical example illustrates the presented theory. |
