Bipolar complex fuzzy semigroups
AIMS Mathematics, 2023 The notion of the bipolar complex fuzzy set (BCFS) is a fundamental notion to be considered for tackling tricky and intricate information. Here, in this study, we want to expand the notion of BCFS by giving a general algebraic structure for tackling ...

Semicrossed Products of Operator Algebras by Semigroups [PDF]
, 2014 We examine the semicrossed products of a semigroup action by $*$-endomorphisms on a C*-algebra, or more generally of an action on an arbitrary operator algebra by completely contractive endomorphisms.

Order, 2022 A mixed lattice is a lattice-type structure consisting of a set with two partial orderings, and generalizing the notion of a lattice. Mixed lattice theory has previously been studied in various algebraic structures, such as groups and semigroups, while ...

Absorption in Invariant Domains for Semigroups of Quantum Channels
Annales de l'Institute Henri Poincare. Physique theorique, 2021 We introduce a notion of absorption operators in the context of quantum Markov processes. The absorption problem in invariant domains (enclosures) is treated for a quantum Markov evolution on a separable Hilbert space, both in discrete and continuous ...

A combinatorial approach to the structure of locally inverse semigroups [PDF]
Semigroup Forum, 2019 This paper introduces a notion of presentation for locally inverse semigroups and develops a graph structure to describe the elements of locally inverse semigroups given by these presentations.

Almost Interior Gamma-ideals and Fuzzy Almost Interior Gamma-ideals in Gamma-semigroups
, 2021 Ideal theory plays an important role in studying in many algebraic structures, for example, rings, semigroups, semirings, etc. The algebraic structure Г-semigroup is a generalization of the classical semigroup. Many results in semigroups were extended to

Dynamical properties and structure of Julia sets of postcritically bounded polynomial semigroups [PDF]
, 2007 We discuss the dynamic and structural properties of polynomial semigroups, a natural extension of iteration theory to random (walk) dynam- ics, where the semigroup G of complex polynomials (under the operation of composition of functions) is such that ...

QUANTUM MECHANICS (GENERAL AND NONRELATIVISTIC) 2357 Controllability properties for finite dimensional quantum Markovian master equations [PDF]
, 2002 Various notions from geometric control theory are used to characterize the behavior of the Markovian master equation for N-level quantum mechanical systems driven by unitary control and to describe the structure of the sets of reachable states.

Monochromatic Sums and Products of Polynomials
Discrete AnalysisMonochromatic sums and products of polynomials, Discrete Analysis 2024:5, 7 pp. An early result in Ramsey theory, Schur's theorem, states that if the positive integers are finitely coloured, then there will always be $x$ and $y$ such that $x,y$ and $x ...
