Fourier multipliers in Banach function spaces with UMD concavifications

open access: yes, 2017
We prove various extensions of the Coifman-Rubio de Francia-Semmes multiplier theorem to operator-valued multipliers on Banach function spaces. Our results involve a new boundedness condition on sets of operators which we call $\ell^{r}(\ell^{s ...

On boundedness of semistable sheaves

open access: yesDocumenta Mathematica, 2022
We give a new simple proof of boundedness of the family of semistable sheaves with fixed numerical invariants on a fixed smooth projective variety. In characteristic zero our method gives a quick proof of Bogomolov's inequality for semistable sheaves on a smooth projective variety of any dimension \ge 2

Generalized Halanay Inequalities and Relative Application to Time-Delay Dynamical Systems

open access: yesMathematics, 2023
A class of generalized Halanay inequalities is studied via the Banach fixed point method and comparison principle. The conditions to ensure the boundedness and stability of the zero solution are obtained in this study.

An Extrapolation of Operator Valued Dyadic Paraproducts

open access: yes, 1996
We consider the dyadic paraproducts $\pi_\f$ on $\T$ associated with an $\M$-valued function $\f.$ Here $\T$ is the unit circle and $\M$ is a tracial von Neumann algebra.

Weighted Pushdown Systems with Indexed Weight Domains [PDF]

open access: yes, 2016
The reachability analysis of weighted pushdown systems is a very powerful technique in verification and analysis of recursive programs. Each transition rule of a weighted pushdown system is associated with an element of a bounded semiring representing ...

boundedness of solutions [PDF]

open access: yes, 2021
This chapter presents the concepts of uniform boundedness, quasiuniform boundedness, and uniform ultimate boundedness in the scenery of generalized ordinary differential equations (ODEs). It includes criteria of uniform boundedness and uniform ultimate boundedness for the generalized ODE.

Impulsive Fractional-Like Differential Equations: Practical Stability and Boundedness with Respect to h-Manifolds

open access: yesFractal and Fractional, 2019
In this paper, an impulsive fractional-like system of differential equations is introduced. The notions of practical stability and boundedness with respect to h-manifolds for fractional-like differential equations are generalized to the impulsive case ...

Boundedness of smooth bilinear square functions and applications to some bilinear pseudo-differential operators

open access: yes, 2010
This paper is devoted to the proof of boundedness of bilinear smooth square functions. Moreover, we deduce boundedness of some bilinear pseudo-differential operators associated with symbols belonging to a subclass of $BS^0_{0,0}$.Comment: 27 ...

The uniform boundedness theorem and a boundedness principle

open access: yesAnnals of Pure and Applied Logic, 2012
Abstract We deal with a form of the uniform boundedness theorem (or the Banach–Steinhaus theorem) for topological vector spaces in Bishop’s constructive mathematics, and show that the form is equivalent to the boundedness principle BD-N , and hence holds not only in classical mathematics but also in intuitionistic mathematics and in constructive
