✦ Synopsis
ln this paper, Jacobi matrix polynomials are introduced, starting from the hypergeometric matrix function. The differential equation satisfied by them is presented. A Rodrigues' formula, orthogonality, and a three terms matrix recurrence relationship are then developed for Jacobi matrix polynomials.

In this paper we introduce the concept of rectangular co-solution of a polynomial matrix equation which permit us to obtain a description of the general solution of systems of higher order differential equations with constant coefficients in a way analogous to the scalar case.
Jacobi approximations in certain Hilbert spaces are investigated. Several weighted inverse inequalities and Poincare inequalities are obtained. Some approximation ŕesults are given. Singular differential equations are approximated by using Jacobi polynomials. This method keeps the spectral accuracy.
