Abstract: | For the polynomials {pn(t)}0, orthonormalized on [–1, 1] with weightp(t) = (1–t) (1+t)v=1m, we obtain necessary and sufficient conditions for boundedness of the sequences of norms: 1) 2) and 3) with the conditions that on [–1, 1] and (H,)–1 L2(0, 2), where(H,) is the modulus of continuity in C(–1, 1) of function H.Translated from Matematicheskie Zametki, Vol. 13, No. 5, pp. 759–770, May, 1973. |
