Soft intersection almost bi-quasi-interior ideals of semigroups [PDF]
Journal of Fuzzy Extension and ApplicationsGeneralizing 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,

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.

Tracing Information Flow from Open Quantum Systems
Laser &Photonics Reviews, Volume 19, Issue 10, May 22, 2025.Integrated optical waveguide arrays are employed for the simulation of an open quantum system, where different degrees of freedom of light are identified with system and environment. This allows to observe non‐Markovian evolution and to study different kinds of information flow between a quantum system and its environment. Abstract Open quantum systems

On the closure of the extended bicyclic semigroup
Karpatsʹkì Matematičnì Publìkacìï, 2011 In the paper we study the semigroup $mathscr{C}_{mathbb{Z}}$which is a generalization of the bicyclic semigroup. We describemain algebraic properties of the semigroup$mathscr{C}_{mathbb{Z}}$ and prove that every non-trivialcongruence $mathfrak{C}$ on the

Regularity and separation for Grušin‐type p‐Laplace operators
Mathematische Nachrichten, Volume 298, Issue 5, Page 1727-1757, May 2025.Abstract We analyze p‐Laplace type operators with degenerate elliptic coefficients. This investigation includes Grušin‐type p‐Laplace operators. We describe a separation phenomenon in elliptic and parabolic p‐Laplace type equations, which provide an illuminating illustration of simple jump discontinuities of the corresponding weak solutions ...

Semigroup 𝐶*-algebras of 𝑎𝑥+𝑏-semigroups [PDF]
Transactions of the American Mathematical Society, 2015 We study semigroupC∗C^*-algebras ofax+bax+b-semigroups over integral domains. The goal is to generalize several results aboutC∗C^*-algebras ofax+bax+b-semigroups over rings of algebraic integers. We prove results concerning K-theory and structural properties like the ideal structure or pure infiniteness. Our methods allow us to treatax+bax+b-semigroups

On the isomorphism problem for monoids of product‐one sequences
Bulletin of the London Mathematical Society, Volume 57, Issue 5, Page 1482-1495, May 2025.Abstract Let G1$G_1$ and G2$G_2$ be torsion groups. We prove that the monoids of product‐one sequences over G1$G_1$ and over G2$G_2$ are isomorphic if and only if the groups G1$G_1$ and G2$G_2$ are isomorphic. This was known before for abelian groups.

Representation of right zero semigroups and their semilattices by a transformation semigroup
Известия высших учебных заведений. Поволжский регион: Физико-математические науки, 2022 Background. As is known, an arbitrary semigroup can be represented by a semigroup of transformations that are right shifts either in this semigroup itself or in the extended semigroup obtained from the original one by adding an outer unit. The problems

Time‐insensitive nonlocal parabolic Harnack estimates
Proceedings of the London Mathematical Society, Volume 130, Issue 5, May 2025.Abstract We establish new Harnack estimates that defy the waiting‐time phenomenon for global solutions to nonlocal parabolic equations. Our technique allows us to consider general nonlocal operators with bounded measurable coefficients. Moreover, we show that a waiting‐time is required for the nonlocal parabolic Harnack inequality when local solutions ...

ON HYBRID INTERIOR IDEALS IN SEMIGROUPS
Проблемы анализа, 2019 In this paper, we introduce the notion of hybrid interior ideals and hybrid characteristic interior ideals of a semigroup. We obtain some equivalent conditions for a hybrid structure to be a hybrid interior ideal of a semigroup.
