Sharp weighted bounds involving A∞
(Mathematical Sciences Publishers, 2013)
We improve on several weighted inequalities of recent interest by replacing a part of the Ap bounds by weaker A∞ estimates involving Wilson’s A∞ constant [w] 0 A∞ := sup Q 1 / w(Q) Z Q M(wχQ). In particular, we show the ...

On the Krall-type polynomials on q-quadratic lattices
(Elsevier, 2011-08)
In this paper, we study the Krall-type polynomials on non-uniform lattices. For these polynomials the second order linear difference equation, q-basic series representation and three-term recurrence relations are obtained. ...

On the practical global uniform asymptotic stability of stochastic differential equations
(Taylor & Francis, 2015-06-04)
The method of Lyapunov functions is one of the most effective ones for the investigation of stability of dynamical systems, in particular, of stochastic differential systems. The main purpose of the paper is the analysis ...

A q-extension of the generalized Hermite polynomials with the continuous orthogonality property on R
(Academic Publications, 2004)
In this paper we study in detail a q-extension of the generalized Hermite polynomials of Szeg˝o. A continuous orthogonality property on R with respect to the positive weight function is established, a q-difference equation ...

The essential norm of a composition operator on Bloch spaces
(Mathematical Sciences Publishers, 1999-04)
We express the essential norm of a composition operator on the Bloch space and the little Bloch space as the asymptotic upper bound of a quantity involving the inducing map and the Pick-Schwarz Lemma. As a consequence, we ...

On the linearization problem involving Pochhammer symbols and their q-analogues
(Elsevier, 1999-07-15)
In this paper we present a simple recurrent algorithm for solving the linearization problem involving some families of q-polynomials in the exponential lattice x(s)=c1qs+c3. Some simple examples are worked out in detail.

On the properties of special functions on the linear-type lattices
(Elsevier, 2013-09-01)
We present a general theory for studying the difference analogues of special functions of hypergeometric type on the linear-type lattices, i.e., the solutions of the second order linear difference equation of hypergeometric ...

Axiomática para el grado muitivaluado
(Real Academia de Ciencias Exactas, Físicas y Naturales, 1988)
In this paper we develop an axiomatic theory for the multivalued degree that preserves the basic properties of the classical degree. We apply it to obtain fixed point theroems and existence of solution fix) = p. We give a ...

Reaction–Diffusion Equation on Thin Porous Media
(Springer, 2021-03-02)
We consider a reaction–diffusion equation on a 3D thin porous media of thickness which is perforated by periodically distributed cylinders of size . On the boundary of the cylinders, we prescribe a dynamical boundary ...

New examples of subsets of c with the FPP and stability of the FPP in hyperconvex spaces
(Springer, 2021-07-22)
The purpose of this work is two-fold. On the one side, we focus on the space of real convergent sequences c where we study non-weakly compact sets with the fixed point property. Our approach brings a positive answer to a ...
