Abstract: | We develop structural formulas satisfied by some families of orthogonal matrix polynomials of size 2 × 2 satisfying second-order differential equations with polynomial coefficients. We consider here three one-parametric families of weight matrices, namely, and and their corresponding orthogonal polynomials. We also show that the orthogonal polynomials with respect to the second family are eigenfunctions of two linearly independent second-order differential operators. |
