The discrete orthogonality relations hold for all the orthogonal polynomials obeying three term recurrence relations. We show that they also multi-indexed Laguerre and Jacobi polynomials, which are new obtained by deforming these classical polynomials. could be considered as a more encompassing characterization of than As start at positive degree ℓD≥1, broken. extra ℓD “lower polynomials,” nece...
