Uniform Boundedness by Averaging

Acta Mathematica Hungarica, 2001
The authors study a system of functional-differential equations with infinite delay. By using Lyapunov functionals, conditions are given for uniform boundedness and uniform ultimate boundedness. The results are based on the method of finding a bound on the averaged values of the unknown solutions and the application of Jensen's inequality. A comparison

Boundedness of Hankel Matrices

Journal of the London Mathematical Society, 1984
Let \((a_{i+j})_{i,j\geq 0}\) be a Hankel matrix with complex elements satisfying the condition \(\sum^{\infty}_{n=0}| a_ n ...

A Theory of Name Boundedness

2013
We develop a theory of name-bounded π-calculus processes, which have a bound on the number of restricted names that holds for all reachable processes. Name boundedness reflects resource constraints in practical reconfigurable systems, like available communication channels in networks and address space limitations in software.

A boundedness lemma for iterations

Journal of Symbolic Logic, 2001
The purpose of this paper is to present a kind of boundedness lemma for direct limits of coarse structural mice, and to indicate some applications to descriptive set theory. For instance, this allows us to show that under large cardinal or determinacy assumptions there is no prewellorder ≤ of length such that for some formula ψ and parameter zif and ...

On the Boundedness of an Economy with Externalities

The Review of Economic Studies, 1973
Establishing the boundedness property of the set of attainable states is an important step in proving the existence of competitive equilibria and/or Pareto optimality for an economy with, as well as without, externalities (cf. Arrow and Debreu [1], Arrow and Hahn [2], Debreu [4] and McKenzie [8], for example).

On Metric Boundedness Structures

Set-Valued Analysis, 1999
In [J. Math. Pures Appl., IX. Sér. 28, 287-320 (1949; Zbl 0041.31602)] \textit{S.-T. Hu} characterized, given a metrizable space \(X\), those families \(\mathcal S\) of subsets of \(X\) for which a compatible metric \(d\) on \(X\) can be found such that \(\mathcal S\) consists of exactly the \(d\)-bounded subsets of \(X\) --- they are the proper ideals

Comparison theorems on boundedness

Funkcialaj Ekvacioj, 1988
The infinite delay equations: \(x'(t)=F(t,x(s);\alpha\leq s\leq t)\), \(t\geq t_*\), \(-\infty \leq \alpha \leq t_*\) as well as the finite delay equations: \(x'(t)=f(t,x_*),\) \(t\geq t_*\) are considered. By using the comparison principle the author establishes several theorems to ensure the uniform boundedness and uniformly ultimate boundedness of ...
