Favard’s Theorem Modulo an Ideal

  • Franciszek Hugon Szafraniec
Part of the Operator Theory: Advances and Applications book series (OT, volume 157)


Recently a treatise [2] dealing with the three term recurrence relation for polynomials orthogonal on algebraic sets was born. Because the paper is pretty sizeable in volume and rich in essence a kind of assistance in the matter as well as some invitation to it has become a need.
