Presentations of inverse semigroups, their kernels and extensions [PDF]

open access: yes, 2011
"Part of this work was done while Gray was an EPSRC Postdoctoral Research Fellow at the University of St Andrews, Scotland"Let S be an inverse semigroup and let π:S→T be a surjective homomorphism with kernel K.

Nonlinear Markov semigroups and interacting Lévy type processes [PDF]

open access: yes, 2007
Semigroups of positivity preserving linear operators on measures of a measurable space X describe the evolutions of probability distributions of Markov processes on X.

Evolution of the Dependence of Residual Lifetimes [PDF]

open access: yes, 2013
We investigate the dependence properties of a vector of residual lifetimes by means of the copula associated with the conditional distribution function.

Computing in matrix groups without memory [PDF]

open access: yes, 2013
Funding: UK Engineering and Physical Sciences Research Council award EP/K033956/1Memoryless computation is a novel means of computing any function of a set of registers by updating one register at a time while using no memory.

Lower semicontinuity of attractors for non-autonomous dynamical systems [PDF]

open access: yes, 2009
This paper is concerned with the lower semicontinuity of attractors for semilinear non-autonomous differential equations in Banach spaces. We require the unperturbed attractor to be given as the union of unstable manifolds of time-dependent hyperbolic

Unary FA-presentable semigroups

open access: yes, 2012
Automatic presentations, also called FA-presentations, were introduced to extend nite model theory to innite structures whilst retaining the solubility of interesting decision problems.

Monochromatic Sums and Products of Polynomials

open access: yesDiscrete Analysis
Monochromatic sums and products of polynomials, Discrete Analysis 2024:5, 7 pp. An early result in Ramsey theory, Schur's theorem, states that if the positive integers are finitely coloured, then there will always be $x$ and $y$ such that $x,y$ and $x ...

Fault‐Tolerant Fuzzy Boundary Control for Nonlinear Distributed Parameter Systems Under Limited Measurements and Markovian Failures

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT This paper proposes a boundary control method for nonlinear distributed parameter systems (DPSs) with limited boundary measurements (BMs), as typically encountered in networked cyber‐physical processes with spatially distributed dynamics such as thermal and biomedical diffusion systems.

Beyond Regular Semigroups [PDF]

open access: yes, 2012
The topic of this thesis is the class of weakly U-abundant semigroups. This class is very wide, containing inverse, orthodox, regular, ample, adequate, quasi-adequate, concordant, abundant, restriction, Ehresmann and weakly abundant semigroups.
