Harmonic Analysis on the Simplex,minded map from the simplex to the positive quadrant of the unit ball is an isomorphism between orthogonal polynomials on the simplex and those orthogonal polynomials on the unit ball that are even in every variable. A large portion of the harmonic analysis on the simplex can be deduced from the corresponding part on the unit ball.
