Some identities involving generalized Gegenbauer polynomials

open access: yesAdvances in Difference Equations, 2017
In this paper, we investigate some interesting identities on the Bernoulli, Euler, Hermite and generalized Gegenbauer polynomials arising from the orthogonality of generalized Gegenbauer polynomials in the generalized inner product 〈 p 1 ( x ) , p 2 ( x )

Scaling for orthogonality

open access: yesIEEE Transactions on Signal Processing, 1993
The accumulated product of orthogonal matrices gradually departs from orthogonality, due to rounding errors. An attractive remedy for this problem, because of its simplicity, consists in renormalizing the columns (scaling) after each partial product.

Matrix interpretation of multiple orthogonality [PDF]

open access: yes, 2010
In this work we give an interpretation of a (s(d + 1) + 1)-term recurrence relation in terms of type II multiple orthogonal polynomials.We rewrite this recurrence relation in matrix form and we obtain a three-term recurrence relation for vector ...

Orthogonality and Dimensionality [PDF]

open access: yesAxioms, 2013
In this article, we present what we believe to be a simple way to motivate the use of Hilbert spaces in quantum mechanics. To achieve this, we study the way the notion of dimension can, at a very primitive level, be defined as the cardinality of a maximal collection of mutually orthogonal elements (which, for instance, can be seen as spatial directions)

Total area based on orthogonal vectors (TAOV) as a novel method of multi-criteria decision aid

open access: yesTechnological and Economic Development of Economy, 2018
Multi criteria decision aid (MCDA) deals with the problem of evaluating a set of finite alternatives regard to a set of finite criteria. A remarkable volume of qualitative and quantitative researches are done on decision making methods and situations ...

A New Approximate Birkhoff Orthogonality Type

open access: yesEuropean Journal of Mathematical Analysis, 2022
In this note, we introduce a new approximate Birkhoff orthogonality type and give a characterization for inner product spaces using the approximate orthogonality.

Remarks on the mean-square values of the geomagnetic field and its components

open access: yesAnnals of Geophysics, 1995
When considering functions on the Earth's (spherical) surface, mean-square values are often used to indicate their (relative) magnitude. If a function is separated into it, (essentially) spherical harmonic components then, provided these individual ...

Zero distributions via orthogonality [PDF]

open access: yes, 2004
We develop a new method to prove asymptotic zero distribution for different kinds of orthogonal polynomials. The method directly uses the orthogonality relations.
