Multi-Integral Representations for Associated Legendre and Ferrers Functions [PDF]

open access: yesSymmetry, 2020
For the associated Legendre and Ferrers functions of the first and second kind, we obtain new multi-derivative and multi-integral representation formulas. The multi-integral representation formulas that we derive for these functions generalize some classical multi-integration formulas. As a result of the determination of these formulae, we compute some

Bounds for Two New Subclasses of Bi-Univalent Functions Associated with Legendre Polynomials [PDF]

open access: yesMathematics, 2021
In this article, two new subclasses of the bi-univalent function class σ related with Legendre polynomials are presented. Additionally, the first two Taylor–Maclaurin coefficients a2 and a3 for the functions belonging to these new subclasses are ...

Inequalities for the Associated Legendre Functions [PDF]

open access: yesJournal of Approximation Theory, 1998
The main results are about the bound for the associated Legendre functions of the first kind \(P_n^m(x)\) with fixed \(x\in [-1,1]\) and integer \(m,n,1\leq | m| \leq n.\) First of all, the author proves a result about transferring upper bounds of the Legendre polynomials \(P_n(x)\) to the functions \(P_n^m(x).\) That result allows to obtain bounds of ...

The Study of Triple Integral Equations with Generalized Legendre Functions [PDF]

open access: yesAbstract and Applied Analysis, 2008
A method is developed for solutions of two sets of triple integral equations involving associated Legendre functions of imaginary arguments. The solution of each set of triple integral equations involving associated Legendre functions is reduced to a ...

Orthogonal Polynomials and Related Special Functions Applied in Geosciences and Engineering Computations [PDF]

open access: yesCommunications, 2010
In applications of mathematics involving either the Laplace or the Helmholtz equation in spherical coordinates the associated Legendre equation occurs. Its solutions are called associated Legendre functions. They have some relations to classical Legendre

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2011
For integral representations of associated Legendre functions in terms of modified Bessel functions, we establish justification for differentiation under the integral sign with respect to parameters.

Some applications of Legendre numbers [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1988
The associated Legendre functions are defined using the Legendre numbers. From these the associated Legendre polynomials are obtained and the derivatives of these polynomials at x=0 are derived by using properties of the Legendre numbers.
