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 <

Chains of congruences on a completely 0-simple semigroup [PDF]
Journal of the Australian Mathematical Society, 1965 Let ρ and σ be two congruences on a completely 0-simple semigroup. Suppose that there is a maximal chain of congruences from ρ to σ which is of finite length. Then, as we shall show, any maximal chain of congruences from ρ to σ finite and of the same length.

Isomorphism problem of power semigroups of completely 0-simple semigroups
Journal of Algebra, 1986 Let S be a semigroup. The power semigroup of S, denoted by \({\mathcal P}(S)\), is defined to be the family of all nonempty subsets of S with the operation defined by \(AB=\{ab:\) \(a\in A\), \(b\in B\) (A,B\(\in {\mathcal P}(S)\}\). If \({\mathcal P}(S_ 1)\simeq {\mathcal P}(S_ 2)\) it is not necessarily true that \(S_ 1\simeq S_ 2\).

Commuting graphs of completely 0-simple semigroups
The aim of this paper is to study commuting graphs of completely $0$-simple semigroups, using the characterization of these semigroups as $0$-Rees matrix semigroups over a groups. We establish a method to decide whether the commuting graph of this semigroup construction is connected or not.

Bipartite graphs and completely 0-simple semigroups
Semigroup Forum, 2011With any completely 0-simple semigroup \(S\), represented as a Rees matrix semigroup \(\mathcal M^0(I,G,\Lambda,P)\), the author associates the bipartite graph \(\Gamma(S)\), the vertex set of which is \(I\cup\Lambda\), the edge set consisting of the pairs \((i,\lambda)\) for which \(p_{\lambda i}\neq 0\).

COMPLETELY 0-SIMPLE SEMIGROUPS OF LEFT QUOTIENTS OF A SEMIGROUP
International Journal of Algebra and Computation, 1996In this paper we investigate the class of all completely 0-simple semigroups of left quotients of a given semigroup S. We show that (if the class is non-empty) it has a ‘greatest’ member ∈S which is in a sense the free completely 0-simple semigroup on S, and describe how the other members can be obtained as homomorphic images of [Formula: see text].
