Some integrals which are not in table 129 of Bierens de Haan

Enno Diekema

In the standard work of Bierens de Haan about integrals we look at table 129. This table lists a number of integrals of a certain kind. In this paper the table is expanded with a n…

Combinatorial identities and hypergeometric series

Enno Diekema

This paper describes a method to find a connection between combinatorial identities and hypergeometric series with a number of examples. Combinatorial identities can often be writt…

Some definite integrals involving Jacobi polynomials

Enno Diekema

Szmytkowski derived a certain integral with Gegenbauer polynomials. A natural generalization is to derive lookalike integrals with Jacobi polynomials. Six methods are treated to de…

The orthogonal Shmaliy polynomials are Hahn polynomials

Enno Diekema

Morales-Mendoza et al. present in 2013 a new class of discrete orthogonal polynomials. They use these polynomials to design an unbiased FIR filter. In their paper they make the sta…

An extension of the orthogonal derivative with adjustable precision

Enno Diekema

The orthogonal derivative is defined as a limit of an integral whose kernel contains an orthogonal polynomial with its measure. When in practice no limit is taken, it means that th…

The two-dimensional fractional orthogonal derivative

Enno Diekema

This paper is an edited and shortened version of Chapter 6 from the thesis of the author. First the one dimensional orthogonal derivative will be extended to the two-dimensional ca…
