Regularity of Semigroups of Transformations Whose Characters Form the Semigroup of a Δ-Structure
International Journal of Mathematics and Mathematical Sciences, 2020 In this paper, we make use of the notion of the character of a transformation on a fixed set X, provided by Purisang and Rakbud in 2016, and the notion of a Δ-structure on X, provided by Magill Jr.

Semigroup approach to birth-and-death stochastic dynamics in continuum [PDF]
, 2011 We describe a general approach to the construction of a state evolution corresponding to the Markov generator of a spatial birth-and-death dynamics in $\mathbb{R}^d$.

Isotopy and equivalence of knots in 3‐manifolds
Journal of the London Mathematical Society, Volume 113, Issue 6, June 2026.Abstract Two knots K$K$ and J$J$ in S3$S^3$ are isotopic if and only if they are related by an orientation‐preserving diffeomorphism of S3$S^3$. This claim follows from the fact that any orientation‐preserving self‐diffeomorphism of S3$S^3$ is isotopic to the identity. We show that this same idea applies to any prime oriented closed 3‐manifold.

On the joins of semigroup varieties with the variety of commutative semigroups [PDF]
Proceedings of the American Mathematical Society, 1994 We show that the join of a variety of semigroups and the variety of all commutative semigroups is not finitely based, provided some weak conditions.

A semigroup-like Property for Discrete Mittag-Leffler Functions
, 2012 Discrete Mittag-Leffler function Eᾱ(λ,z) of order 0 < α ≤ 1, E1̄(λ,z)=(1-λ)-z, λ ≠ 1, satisfies the nabla Caputo fractional linear difference equation C∇0αx(t)=λx(t),x(0)=1,t∈ℕ1={1,2,3,…}. Computations can show that the semigroup identity Eᾱ(λ,z1)Eᾱ

The cone of functionals on the Cuntz semigroup [PDF]
, 2011 The functionals on an ordered semigroup S in the category Cu--a category to which the Cuntz semigroup of a C*-algebra naturally belongs--are investigated.

A priori bounds for the generalised parabolic Anderson model
Communications on Pure and Applied Mathematics, Volume 79, Issue 5, Page 1315-1394, May 2026.Abstract We show a priori bounds for solutions to (∂t−Δ)u=σ(u)ξ$(\partial _t - \Delta) u = \sigma (u) \xi$ in finite volume in the framework of Hairer's Regularity Structures [Invent Math 198:269–504, 2014]. We assume σ∈Cb2(R)$\sigma \in C_b^2 (\mathbb {R})$ and that ξ$\xi$ is of negative Hölder regularity of order −1−κ$- 1 - \kappa$ where κ<κ¯$\kappa <

ON INVERSE SEMIGROUP C ∗ -ALGEBRAS AND CROSSED PRODUCTS [PDF]
, 2011 We describe the C -algebra of an E-unitary or strongly 0- E-unitary inverse semigroup as the partial crossed product of a commu- tative C -algebra by the maximal group image of the inverse semigroup.

Stochastic Dynamics From Maximum Entropy in Action Space
Fortschritte der Physik, Volume 74, Issue 5, May 2026.ABSTRACT We develop an information‐theoretic formulation of stochastic dynamics in which the fundamental stochastic variable is the total action connecting spacetime points, rather than individual paths. By maximizing Shannon entropy over a joint distribution of actions and endpoints, subject to normalization and a constraint on the mean action, we ...

The principal bundles over an inverse semigroup
, 2016 This paper is a contribution to the development of the theory of representations of inverse semigroups in toposes. It continues the work initiated by Funk and Hofstra. For the topos of sets, we show that torsion-free functors on Loganathan\u27s category $
