Density functions for epsilon multiplicity and families of ideals

Journal of the London Mathematical Society, Volume 111, Issue 4, April 2025.
Abstract A density function for an algebraic invariant is a measurable function on R$\mathbb {R}$ which measures the invariant on an R$\mathbb {R}$‐scale. This function carries a lot more information related to the invariant without seeking extra data.

Rank Properties of the Semigroup of Endomorphisms over Brandt semigroup [PDF]

arXiv, 2017
Howie and Ribeiro \cite{a.Howie99,a.Howie00} introduced various ranks, viz. small rank, lower rank, intermediate rank, upper rank and the large rank of a finite semigroup. In this note, we investigate all these ranks of the semigroup of endomorphisms over Brandt semigroup.

Γ – semigroup generated by a semigroup

Journal of Physics: Conference Series, 2020
Abstract In Γ – semigroup S, the element of Γ maybe a binary operation in S. Every element of any semigroupS can define a binary operation in S. A collection of binary operations defined of the element of S generates Γ – semigroup S.

From the conformal anomaly to the Virasoro algebra

Proceedings of the London Mathematical Society, Volume 130, Issue 4, April 2025.
Abstract The conformal anomaly and the Virasoro algebra are fundamental aspects of two‐dimensional conformal field theory and conformally covariant models in planar random geometry. In this article, we explicitly derive the Virasoro algebra from an axiomatization of the conformal anomaly in terms of real determinant lines, one‐dimensional vector spaces

On identities of indicator burnside semigroups [PDF]

arXiv, 2010
A semigroup variety is said to be a Rees-Sushkevich variety if it is contained in a periodic variety generated by 0-simple semigroups. S. I. Kublanovsky has proven that a variety V is a Rees-Sushkevich variety if and only it does not contain any of special finite semigroups. These semigroups are called indicator Burnside semigroups.

Stabilization for degenerate equations with drift and small singular term

Mathematical Methods in the Applied Sciences, Volume 48, Issue 4, Page 5086-5109, 15 March 2025.
We consider a degenerate/singular wave equation in lone dimension, with drift and in presence of a leading operator that is not in divergence form. We impose a homogeneous Dirichlet boundary condition where the degeneracy occurs and a boundary damping at the other endpoint.

Embedding of graph inverse semigroups into CLP-compact topological semigroups [PDF]

arXiv, 2018
In this paper we investigate graph inverse semigroups which are subsemigroups of compact-like topological semigroups. More precisely, we characterise graph inverse semigroups which admit a compact semigroup topology and describe graph inverse semigroups which can be embeded densely into CLP-compact topological semigroups.

Fuzzy semigroups via semigroups

, 2023
The theory of fuzzy semigroups is a branch of mathematics that arose in early 90's as an effort to characterize properties of semigroups by the properties of their fuzzy subsystems which include, fuzzy subsemigroups and their alike, fuzzy one (resp. two) sided ideals, fuzzy quasi-ideals, fuzzy bi-ideals etc.

Stability of N‐front and N‐back solutions in the Barkley model

GAMM-Mitteilungen, Volume 48, Issue 1, March 2025.
ABSTRACT In this article, we establish for an intermediate Reynolds number domain the stability of N$$ N $$‐front and N$$ N $$‐back solutions for each N>1$$ N>1 $$ corresponding to traveling waves, in an experimentally validated model for the transition to turbulence in pipe flow proposed in [Barkley et al., Nature 526(7574):550‐553, 2015]. We base our

Soft intersection almost bi-quasi-interior ideals of semigroups [PDF]

Journal of Fuzzy Extension and Applications
Generalizing the ideals of an algebraic structure has shown to be both exciting and valuable to mathematicians. In this context, the concept of Bi-Quasi-Interior Ideal (BQI-ideal) was proposed as a generalization of interior ideal, quasi-ideal, bi-ideal,
