RT Journal Article T1 On two models of orthogonal polynomials and their applications A1 Arvesú Carballo, Jorge A1 Marcellán Español, Francisco José AB This contribution deals with some models of orthogonal polynomials as well as their applications in several areas of mathematics. Some new trends in the theory of orthogonal polynomials are summarized.In particular, we emphasize on two kinds of orthogonality, i.e., the standard orthogonality in the unit circle and a non standard one, which is called multi-orthogonality. Both have attracted the interest of researchers during the past ten years.
