Matrix valued Hermite polynomials, Burchnall formulas and non-abelian Toda lattice
(Academic Press Inc Elsevier Science, 2019-09)
A general family of matrix valued Hermite type orthogonal polynomials is introduced as the matrix orthogonal polynomials with respect to a weight. The matrix polynomials are eigenfunctions of a matrix differential equation. ...
A non-standard generating function for continuous dual q-hahn polynomials
(Centro de Investigaciones en Matemática Pura y Aplicada (CIMPA) y Escuela de Matemática, San José, Costa Rica., 2011)
PBW deformations of a Fomin–Kirillov Algebra and other examples
We begin the study of PBW deformations of graded algebras relevant to the theory of Hopf algebras. One of our examples is the Fomin–Kirillov algebra E3. Another one appeared in a paper of García Iglesias and Vay. As a ...
Polynomial stability of a joint-leg-beam system with local damping
Recent advances in the design and construction of large inflatable/rigidizable space structures and potential new applications of such structures have produced a demand for better analysis and computational tools to deal ...

Optimal polynomial stability for laminated beams with Kelvin–Voigt damping
In this manuscript, we study the asymptotic behavior of two laminated beams systems formed by two identical layers of uniform thickness, whose surfaces are held together by an adhesive layer that allows interfacial sliding. ...
Hypercyclic convolution operators on Fréchet spaces of analytic functions
(Academic Press Inc Elsevier Science, 2007-12)
A result of Godefroy and Shapiro states that the convolution operators on the space of entire functions on Cn, which are not multiples of identity, are hypercyclic. Analogues of this result have appeared for some spaces ...
