An Efficient Legendre–Galerkin Approximation for Fourth-Order Elliptic Problems with SSP Boundary Conditions and Variable Coefficients

open access: yesMathematics, 2023
Under simply supported plate (SSP) boundary conditions, a numerical method based on the higher-order Legendre polynomial approximation was studied and developed for fourth-order problems with variable coefficients.

On computation of Hough functions [PDF]

open access: yesGeoscientific Model Development, 2016
Hough functions are the eigenfunctions of the Laplace tidal equation governing fluid motion on a rotating sphere with a resting basic state. Several numerical methods have been used in the past.

On Some Relations between the Hermite Polynomials and Some Well-Known Classical Polynomials and the Hypergeometric Function.

open access: yesمجلة العلوم البحتة والتطبيقية, 2020
The connection between different classes of special functions is a very important aspect in establishing new properties of the related classical functions that is they can inherit the properties of each other. Here we show how the Hermite polynomials are

Note on the Integrals of Products of Associated Legendre Functions [PDF]

open access: yesThe Computer Journal, 1964
Although closed-form expressions are available in particular cases (Gaunt, 1929), they are, in general, unattractive for machine use. Other expressions for the general case have been given (Miller, 1963; Joy, 1962), but have been found comparatively less convenient for the computation of IK than the method suggested in the present work.

Mutually inverse series relating Ferrers and associated Legendre functions and generating functions pertaining to them [PDF]

open access: yes, 2023
This article deals with three types of mutually inverse series relating Ferrers and associated Legendre functions of arbitrary complex indexes and orders established on the base of integral representations by using a number of generating functions (some ...
