An Introduction to the q-Laguerre-Hahn Orthogonal q-Polynomials
Symmetry, Integrability and Geometry: Methods and Applications, 2011 Orthogonal q-polynomials associated with q-Laguerre-Hahn form will be studied as a generalization of the q-semiclassical forms via a suitable q-difference equation. The concept of class and a criterion to determinate it will be given.

Difference Sturm--Liouville problems in the imaginary direction
, 2011 We consider difference operators in $L^2$ on $\R$ of the form $$ L f(s)=p(s)f(s+i)+q(s) f(s)+r(s) f(s-i) ,$$ where $i$ is the imaginary unit. The domain of definiteness are functions holomorphic in a strip with some conditions of decreasing at infinity ...

Advanced Optical Materials, Volume 13, Issue 30, October 24, 2025.This study presents the replication of micro‐optics fabricated by two‐photon polymerization grayscale lithography via electroplating and injection molding, enabling mass production without loss of precision. A diffractive aspherical micro‐lens array is fabricated and replicated, and its performance is compared before and after replication ...

Body Size and Risk of Death During the 1918 Influenza Pandemic in Alaska
American Journal of Human Biology, Volume 37, Issue 10, October 2025.ABSTRACT In the aftermath of the 2009 H1N1 influenza A pandemic, research revealed the relationship between body size and the severity of influenza outcomes. However, there is little data available on body size in historical populations; therefore, the relationship between body size and 1918 influenza pandemic outcomes is virtually unknown.

An addition theorem for someq-Hahn polynomials
Monatshefte f�r Mathematik, 1978 Theq-Hahn polynomials appear as functions on the lattice of subspaces of a finite-dimensional vector space over a finite field. Irreducible representations of the related general linear group are restricted to a maximal parabolic subgroup, and a specific description of the resulting irreducible components leads to an addition formula.

Laguerre–Hahn orthogonal polynomials on the real line [PDF]
Random Matrices: Theory and Applications, 2019 A survey is given on sequences of orthogonal polynomials related to Stieltjes functions satisfying a Riccati type differential equation with polynomial coefficients — the so-called Laguerre–Hahn class. The main goal is to describe analytical aspects, focusing on differential equations for those orthogonal polynomials, difference and differential ...

Deformed su(1,1) Algebra as a Model for Quantum Oscillators
Symmetry, Integrability and Geometry: Methods and Applications, 2012 The Lie algebra su(1,1) can be deformed by a reflection operator, in such a way that the positive discrete series representations of su}(1,1) can be extended to representations of this deformed algebra su(1,1)_gamma.
