Multiplication Operators on Orlicz Generalized Difference (sss)

open access: yesJournal of Function Spaces, 2020
In this article, we inspect the sufficient conditions on the Orlicz generalized difference sequence space to be premodular Banach (sss). We look at some topological and geometrical structures of the multiplication operators described on Orlicz ...

A note on fractional difference operators

open access: yesAlexandria Engineering Journal, 2018
In the present article, following on very recent and new approach of fractional difference operator by Baliarsingh (2016), we establish some new ideas involving the exponent rules of this operator.

Resolvent Convergence for Differential–Difference Operators with Small Variable Translations

open access: yesMathematics, 2023
We consider general higher-order matrix elliptic differential–difference operators in arbitrary domains with small variable translations in lower-order terms.

On the difference between the ‘In’ and ‘According to’ operators

open access: yesLinguistics and Philosophy, 2023
Semanticists and philosophers of fiction that formulate analyses of reports on the content of media—or ‘contensive statements’—of the form ‘In/According to s, p’, usually treat the ‘In s’-operator (In) and the ‘According to s’-operator (Acc) on a par.

Chaotic finite difference operators

open access: yesChaos: An Interdisciplinary Journal of Nonlinear Science, 2023
In this article, we analyze the chaotic behavior of finite difference operators associated with certain differential equations. Our examples range from numerical schemes for a birth-and-death model with proliferation to a class of second-order partial differential equations that includes the hyperbolic heat transfer equation, the telegraph equation ...

COMPACT DIFFERENCES OF COMPOSITION OPERATORS [PDF]

open access: yesBulletin of the Australian Mathematical Society, 2008
AbstractLet ϕ andψbe analytic self-maps of the open unit disk. Each of them induces a composition operator,CϕandCψrespectively, acting between weighted Bergman spaces of infinite order. We show that the differenceCϕ−Cψis compact if and only if both operators are compact or both operators are not compact and the pseudohyperbolic distance of the ...

Resonances for Difference Operators

open access: yesJournal of Mathematical Analysis and Applications, 1995
The author shows the existence of resonances for the difference operators \(H\) on \(\ell^2(\mathbb{Z})\), defined by \(D^* D+ V\), where \(D: \varphi(n)\mapsto \varphi(n+ 1)- \varphi(n)\), \(D^*: \varphi(n)\mapsto \varphi(n)- \varphi(n- 1)\), and barrier potential \(V\), multiplication by a real-valued function on \(\mathbb{Z}\), \(\text{supp } V ...

Mezocontinuous operators and solutions of difference equations

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2016
We attempt to unify and extend the theory of asymptotic properties of solutions to difference equations of various types. Usually in difference equations some functions are used which generate transformations of sequences. We replace these functions by

Symmetrizable finite difference operators [PDF]

open access: yesMathematics of Computation, 1990
We introduce the notion of a symmetrizable finite difference operator and prove that such operators are stable. We then present some sufficient conditions for symmetrizability. One of these extends H.-O. Kreiss’ theorem on dissipative difference schemes for hyperbolic equations to a more general case with full (

Are Fertility Preservation Procedures Before Gonadotoxic Therapy and Hematopoietic Stem Cell Transplantation Feasible and Safe in Very Young Children? A Retrospective Cohort Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Fertility preservation (FP) is increasingly integrated into the care of pediatric patients exposed to gonadotoxic therapy or conditioning for hematopoietic stem cell transplantation (HSCT), yet perioperative data in infants and toddlers remain scarce.
