MONOID ACTIONS AND ULTRAFILTER METHODS IN RAMSEY THEORY

open access: yesForum of Mathematics, Sigma, 2019
First, we prove a theorem on dynamics of actions of monoids by endomorphisms of semigroups. Second, we introduce algebraic structures suitable for formalizing infinitary Ramsey statements and prove a theorem that such statements are implied by the ...

Underlying SUSY in a generalized Jaynes–Cummings model

open access: yesScientific Reports, 2021
We present a general qubit-boson interaction Hamiltonian that describes the Jaynes–Cummings model and its extensions as a single Hamiltonian class. Our model includes non-linear processes for both the free qubit and boson field as well as non-linear ...

An extension of the disc algebra, I [PDF]

open access: yesBulletin of the London Mathematical Society, 2012
We identify all uniform limits of polynomials on the closed unit disc with respect to the chordal metric \c{hi} . One such limit is f=oo. The other limits are holomorphic functions f:-->C so that for every ζ in the boundary of unit disc D the limf(z) while z-->ζ exists in C U {oo}. The class of the above functions is denoted by A(D)~.

Coefficients of algebraic functions: formulae and asymptotics [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2013
This paper studies the coefficients of algebraic functions. First, we recall the too-little-known fact that these coefficients $f_n$ have a closed form. Then, we study their asymptotics, known to be of the type $f_n \sim C A^n n^{\alpha}$.

The Weak Variable Sharing Property

open access: yesBulletin of the Section of Logic, 2023
An algebraic type of structure is shown forth which is such that if it is a characteristic matrix for a logic, then that logic satisfies Meyer's weak variable sharing property.

Application of the Neutrosophic Fuzzy Sets in Profession Determination [PDF]

open access: yesNeutrosophic Sets and Systems
We present several operations, such as algebraic sum, algebraic product, and arithmetic mean, over the neutrosophic sets extended with moment in time and sketch numbers.

A short history of algebraic statistics [PDF]

open access: yes, 2008
In algebraic statistics, computational techniques from algebraic geometry become tools to address statistical problems. This, in turn, may prompt research in algebraic geometry. The basic ideas at the core of algebraic statistics will be presented. In

Fixpointed Idempotent Uninorm (Based) Logics

open access: yesMathematics, 2019
Idempotent uninorms are simply defined by fixpointed negations. These uninorms, called here fixpointed idempotent uninorms, have been extensively studied because of their simplicity, whereas logics characterizing such uninorms have not.

Noncommutative coding theory and algebraic sets for skew PBW extensions [PDF]

open access: yes, 2023
The classical commutative coding theory has been recently extended to noncommutative rings of polynomial type. There are many interesting works in coding theory over single Ore extensions.

Risk Measures’ Duality on Ordered Linear Spaces

open access: yesMathematics
The aim of this paper is to provide a dual representation of convex and coherent risk measures in partially ordered linear spaces with respect to the algebraic dual space. An algebraic robust representation is deduced by weak separation of convex sets by
