Convolutions of sets with bounded VC-dimension are uniformly continuous

open access: yesDiscrete Analysis, 2021
Convolutions of sets with bounded VC-dimension are uniformly continuous, Discrete Analysis 2021:1, 25 pp. In recent years there has been a cross-fertilization between combinatorics and model theory, as a result of the realization that certain model ...

Using the scaled boundary finite element method to model 2D time-dependent geotechnical engineering problems [PDF]

open access: yes, 2005
The scaled boundary finite element method caters well for soil-structure interaction problems, but the formulation does not cater for the presence of changing pore pressures with time, body loads and tractions. A detailed formulation is presented in this

The Existence and Application of Unbounded Connected Components

open access: yesJournal of Applied Mathematics, 2014
Let X be a Banach space and Cn a family of connected subsets of R×X. We prove the existence of unbounded components in superior limit of {Cn}, denoted by lim¯ Cn, which have prescribed shapes.

Fremlin tensor product respects the unbounded convergences [PDF]

open access: yes, 2023
Suppose $\Sigma$ is a topological space and $S(\Sigma)$ is the vector lattice of all continuous real-valued functions defined on open dense subsets of $\Sigma$. In this paper, we establish some lattice and topological aspects of $S(\Sigma)$.

Unbounded-time analysis of guarded LTI systems with inputs by abstract acceleration

open access: yes, 2015
Linear Time Invariant (LTI) systems are ubiquitous in software systems and control applications. Unbounded-time reachability analysis that can cope with industrial-scale models with thousands of variables is needed. To tackle this general problem, we use

Characterisation of CD8neg and CD8+ human natural killer cell subsets [PDF]

open access: yes, 2012
NK cells are CD3neg CD56+ lymphocytes that constitute about 10-15% of peripheral blood lymphocytes. They have an innate ability to recognise and kill virus infected cells and tumour cells.

Constructing Union-Free pairs of K-Element subsets [PDF]

open access: yes, 2013
It is proved that one can choose [1/2(n/k)] disjoint pairs of k-element subsets of an n-element set in such a way that the unions of the pairs are all different, supposing that n > n(k)

Extensions defined using bornologies

open access: yesApplied General Topology, 2013
Many extensions of a space X such that the remainder Y is closed can be constructed as B-extensions, that is, by defining a topology on the disjoint union X [ Y , provided there exists a map, satisfying some conditions, from a basis of Y into the family ...

Random fixed point theorems for a random operator on an unbounded subset of a Banach space

open access: yesApplied Mathematics Letters, 2008
The authors obtain random fixed point theorems for nonexpansive random operators and claim to improve certain results of \textit{G.\,Isac} and \textit{S.\,Z.\thinspace Németh} [J.~Math.\ Anal.\ Appl.\ 314, No.\,2, 500--512 (2006; Zbl 1090.47041)] and \textit{J.--P.\thinspace Penot} [Proc.\ Am.\ Math.\ Soc.\ 131, No.\,8, 2371--2377 (2003; Zbl 1035.47043)
