Algebraic interpretation of the two-variable Jacobi polynomials on the triangle: the pentagonal way

Nicolas Crampé, Quentin Labriet, Lucia Morey +3

The rank two Jacobi algebra $J_{2}$ is used to provide an interpretation of the two-variable Jacobi polynomials $J_{n, k}^{(a, b, c)} (x, y)$ on the triangle, as overlaps betwee…
