RECURRENCE RELATIONS FOR SOBOLEV ORTHOGONAL POLYNOMIALS
Проблемы анализа, 2020 We consider recurrence relations for the polynomials orthonormal with respect to the Sobolev-type inner product and generated by classical orthogonal polynomials, namely: Jacobi polynomials, Legendre polynomials, Chebyshev polynomials of the first and ...

Numerically Stable Recurrence Relations for the Communication Hiding Pipelined Conjugate Gradient Method [PDF]
IEEE Transactions on Parallel and Distributed Systems, 2019 Pipelined Krylov subspace methods (also referred to as communication-hiding methods) have been proposed in the literature as a scalable alternative to classic Krylov subspace algorithms for iteratively computing the solution to a large linear system in ...

A converse of Sturm's separation theorem
Electronic Journal of Qualitative Theory of Differential Equations, 2021 We show that Sturm's classical separation theorem on the interlacing of the zeros of linearly independent solutions of real second order two-term ordinary differential equations necessarily fails in the presence of a turning point in the principal part ...

Axioms, 2022 The paper deals with the problem of expansion of the ratios of the confluent hypergeometric function of N variables ΦD(N)(a,b¯;c;z¯) into the branched continued fractions (BCF) of the general form with N branches of branching and investigates the ...

Three- and four-electron integrals involving Gaussian geminals: Fundamental integrals, upper bounds, and recurrence relations. [PDF]
Journal of Chemical Physics, 2017 We report the three main ingredients to calculate three- and four-electron integrals over Gaussian basis functions involving Gaussian geminal operators: fundamental integrals, upper bounds, and recurrence relations.

Recurrence Relations for a Family of Orthogonal Polynomials on a Triangle [PDF]
Lecture Notes in Computational Science and Engineering, 2018 This paper derives sparse recurrence relations between orthogonal polynomials on a triangle and their partial derivatives, which are analogous to recurrence relations for Jacobi polynomials.

Recurrence relations for symplectic realization of (quasi)-Poisson structures [PDF]
Journal of Physics A: Mathematical and Theoretical, 2018 It is known that any Poisson manifold can be embedded into a bigger space which admits a description in terms of a global symplectic structure. Such a procedure is known as a symplectic realization and has a number of important applications like the ...

Determinantal expressions and recurrence relations for Fubini and Eulerian polynomials
Journal of Interdisciplinary Mathematics, 2019 In the paper, by virtue of an explicit formula for higher order derivatives of the ratio between two differentiable functions in terms of the Hessenberg determinant, the author presents determinantal expressions and recurrence relations for generalized ...
