Unary FA-presentable semigroups [PDF]

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.

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.

On maximal subgroups of free idempotent generated semigroups [PDF]

open access: yes, 2011
We prove the following results: (1) Every group is a maximal subgroup of some free idempotent generated semigroup. (2) Every finitely presented group is a maximal subgroup of some free idempotent generated semigroup arising from a finite semigroup.

Growth of generating sets for direct powers of classical algebraic structures [PDF]

open access: yes, 2012
For an algebraic structure A denote by d(A) the smallest size of a generating set for A, and let d(A)=(d(A),d(A2),d(A3),…), where An denotes a direct power of A.

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.

Semilatice decompositions of semigroups. Hereditariness and periodicity—An overview [PDF]

open access: yes, 2020
A semigroup is an algebraic structure consisting of a set with an associative binary operation defined on it. We can say that most of the work within theory is done on semigroups with a finiteness condition, i.e.

Fast Fourier transforms for finite inverse semigroups [PDF]

open access: yes, 2009
We extend the theory of fast Fourier transforms on finite groups to finite inverse semigroups. We use a general method for constructing the irreducible representations of a finite inverse semigroup to reduce the problem of computing its Fourier transform

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.
