- (M, N)–coherent pairs of order (m, k) and Sobolev orthogonal polynomialsPublication . Jesus, Márcio; Marcellan, Francisco; Petronilho, José; Pinzón-Cortés, NataliaA pair of regular linear functionals ( U, V ) is said to be a ( M ,N ) -coherent pair of order ( m ,k ) if their corresponding sequences of monic orthogonal polynomials (…)
- Sobolev orthogonal polynomials and (M, N)-coherent pairs of measuresPublication . Jesus, Márcio; Petronilho, JoséWe introduce the notion of (M, N) −coherent pair of measures as a generalization of the concept of coherent pair of measures introduced by Iserles et al. [A. Iserles, P.E.Koch,S.P.Nørsett,J.M.Sanz-Serna,Onpolynomialsorthogonalwithrespecttocertain Sobolev inner products, J. Approx. Theory 65(2) (1991) 151–175], and subsequently Generalized by several authors. A pair of measures (…)
