Cyclic projectors and separation theorems in idempotent convex geometry

open access: yes, 2007
Semimodules over idempotent semirings like the max-plus or tropical semiring have much in common with convex cones. This analogy is particularly apparent in the case of subsemimodules of the n-fold cartesian product of the max-plus semiring it is known ...

Higher Lie Idempotents

open access: yesJournal of Algebra, 1999
The Milnor-Moore theorem says that in characteristic zero, any connected graded cocommutative bialgebra \(A\) is canonically isomorphic to the enveloping bialgebra of the Lie algebra of its primitive elements \(\text{Prim}(A)\). There is a weaker form known as the Leray theorem, whose dual statement is that any retract of the vector space inclusion of \

Equilibria for games in idempotent measures

open access: yesESAIM: Proceedings and Surveys, 2017
This paper is devoted to non-cooperative games in idempotent measures. We consider two kinds of such games. Firstly, players are allowed to play their mixed idempotent strategies.

The idempotent Radon--Nikodym theorem has a converse statement

open access: yes, 2013
Idempotent integration is an analogue of the Lebesgue integration where $\sigma$-additive measures are replaced by $\sigma$-maxitive measures. It has proved useful in many areas of mathematics such as fuzzy set theory, optimization, idempotent analysis ...

An Introduction to The Split-Complex Symbolic 2-Plithogenic Numbers [PDF]

open access: yesNeutrosophic Sets and Systems, 2023
The objective of this paper is to combine split-complex numbers with symbolic 2-plithogenic numbers in one algebraic structure called split-complex symbolic 2-plithogenic real numbers.

Self-adjoint symmetry operators connected with the magnetic Heisenberg ring

open access: yes, 2009
We consider symmetry operators a from the group ring C[S_N] which act on the Hilbert space H of the 1D spin-1/2 Heisenberg magnetic ring with N sites. We investigate such symmetry operators a which are self-adjoint (in a sence defined in the paper) and ...

Idempotents in Matrix Rings [PDF]

open access: yesProceedings of the American Mathematical Society, 1994
Let R be a commutative, von Neumann regular ring and M n ( R ) {M_n}(R) the ring of n × n n \times n matrices over R. What are the idempotents in M n (

On the Open Problem Related to Rank Equalities for the Sum of Finitely Many Idempotent Matrices and Its Applications

open access: yesThe Scientific World Journal, 2014
Tian and Styan have shown many rank equalities for the sum of two and three idempotent matrices and pointed out that rank equalities for the sum P1+⋯+Pk with P1,…,Pk be idempotent (k>3) are still open.

Rings in which every unit is a sum of a nilpotent and an idempotent [PDF]

open access: yes, 2017
A ring $R$ is a UU ring if every unit is unipotent, or equivalently if every unit is a sum of a nilpotent and an idempotent that commute. These rings have been investigated in C\u{a}lug\u{a}reanu \cite{C} and in Danchev and Lam \cite{DL}.
