Multiple orthogonal polynomials [PDF]
Journal of Computational and Applied Mathematics, 1998 This is a review of the advances in the theory of simultaneous Padé approximants for the past five years. It covers new results in the classification of what appear to be the semiclassical multiple orthogonal polynomials, new applications to number theory, connections with the spectral theory of non-symmetric operators and orthogonal polynomials with ...

Sextic anharmonic oscillators and orthogonal polynomials
, 2006 Under certain constraints on the parameters a, b and c, it is known that Schroedinger's equation -y"(x)+(ax^6+bx^4+cx^2)y(x) = E y(x), a > 0, with the sextic anharmonic oscillator potential is exactly solvable.

Agribusiness, EarlyView.Abstract Packaging of fresh fruits and vegetables is standard in many grocery stores. This mixed methods study aims to identify the role packaging plays in consumer choice and what packaging material consumers prefer. We analyzed data from quantitative stated preference experiments with a quota sample of 485 consumers living in Germany.

On 2-orthogonal polynomials of Laguerre type
International Journal of Mathematics and Mathematical Sciences, 1999 Let {Pn}n≥0 be a sequence of 2-orthogonal monic polynomials relative to linear functionals ω0 and ω1 (see Definition 1.1). Now, let {Qn}n≥0 be the sequence of polynomials defined by Qn:=(n+1)−1P′n+1,n≥0.

, 2012 A set of generalized squeezed-coherent states for the finite u(2) oscillator is obtained. These states are given as linear combinations of the mode eigenstates with amplitudes determined by matrix elements of exponentials in the su(2) generators.

Agribusiness, EarlyView.ABSTRACT Vending is an important sector in the daily lives of many people, and coffee is the most frequently consumed product in the European market. Like many other sectors, vending is responding to the challenge of sustainable development by taking various actions, such as offering increasingly ecologically sound coffee while maintaining/improving ...

A Dunkl-classical d-symmetric d-orthogonal polynomial set [PDF]
Rendiconti di Matematica e delle Sue Applicazioni, 2010 In this paper, we apply a d-orthogonality preserving operator to the Humbert polynomials to derive a new Dunkl-classical d-orthogonal polynomials generalizing the Humbert ones.

On derivatives of orthogonal polynomials. II [PDF]
Bulletin of the American Mathematical Society, 1936 m{x)(j)n{x)d\p(x) = 0, I d\p(x) > 0, (m 7* n), a J a where \[/(x) is a non-decreasing function of bounded variation. There is no restriction in assuming the highest coefficient 1. It has been shown by W. Hahnf that if the derivatives also form a set of orthogonal polynomials, then the original set were Jacobi, Hermite, or Laguerre polynomials.

Agribusiness, EarlyView.ABSTRACT Social tensions and resource depletion pose significant challenges to the agri‐food sector, highlighting the need for coordinated strategies to ensure sustainability in supply chains. Despite its critical importance, the relationship between coordination mechanisms and sustainability performance remains underexplored.

Recurrence Relations for Orthogonal Polynomials on Triangular Domains
Mathematics, 2016 In Farouki et al, 2003, Legendre-weighted orthogonal polynomials P n , r ( u , v , w ) , r = 0 , 1 , … , n , n ≥ 0 on the triangular domain T = { ( u , v , w ) : u , v , w ≥ 0 , u + v + w = 1 } are constructed, where u , v , w
