DMA:an algebra for multicriteria spatial modeling [PDF]
, 2006 The objective of this paper is to propose a new algebra, called decision map algebra (DMA), especially devoted to multicriteria spatial modeling. DMA is a generic and context-independent modeling language inspired from map algebra and other similar ...

Nonlinear Skew Lie-Type Derivations on ∗-Algebra
, 2023 Let A be a unital ∗-algebra over the complex fields C. For any H1,H2∈A, a product [H1,H2]•=H1H2−H2H1* is called the skew Lie product. In this article, it is shown that if a map ξ : A→A (not necessarily linear) satisfies ξ

Nilpotent subspaces of maximal dimension in semisimple Lie algebras [PDF]
, 2006 We show that a linear subspace of a reductive Lie algebra g that consists of nilpotent elements has dimension at most equal to the number of positive roots, and that any nilpotent subspace attaining this upper bound is equal to the nilradical of a Borel ...

Local charges in involution and hierarchies in integrable sigma-models
Journal of High Energy Physics, 2017 Integrable σ-models, such as the principal chiral model, ℤ T $$ {\mathbb{Z}}_T $$ -coset models for T ∈ ℤ ≥ 2 $$ T\in {\mathbb{Z}}_{\ge 2} $$ and their various integrable deformations, are examples of non-ultralocal integrable field theories described by

On new universal realizability criteria
Special Matrices, 2022 A list Λ={λ1,λ2,…,λn}\Lambda =\left\{{\lambda }_{1},{\lambda }_{2},\ldots ,{\lambda }_{n}\right\} of complex numbers is said to be realizable if it is the spectrum of an entrywise nonnegative matrix and is said to be universally realizable (UR), if it is

Pseudo GE-Algebras as the Extension of GE-Algebras
Kragujevac Journal of MathematicsIn this paper, the notion of a pseudo GE-algebra as an extension of a GE-algebra is introduced. Basic properties of pseudo GE-algebras are described. The concepts of strong pseudo BE-algebra, good pseudo BE-algebra, good pseudo GE-algebra, and the relationship between them are established.

On generalized Melvin solution for the Lie algebra $$E_6$$ E6
European Physical Journal C: Particles and Fields, 2017 A multidimensional generalization of Melvin’s solution for an arbitrary simple Lie algebra $${\mathcal {G}}$$ G is considered. The gravitational model in D dimensions, $$D \ge 4$$ D≥4 , contains n 2-forms and $$l \ge n$$ l≥n scalar fields, where n is the

Maximal Injective Real W∗-Subalgebras of Tensor Products of Real W∗-Algebras
Abstract and Applied Analysis, 2022 It is known that injective (complex or real) W∗-algebras with particular factors have been studied well enough. In the arbitrary cases, i.e., in noninjective case, to investigate (up to isomorphism) W∗-algebras is hard enough, in particular, there exist ...

Observer‐Based Adaptive Event‐Triggered Tracking Control for Fuzzy TS Systems With Premise Mismatch
International Journal of Adaptive Control and Signal Processing, EarlyView.This paper presents an adaptive logistic event‐triggered observer‐based tracking controller for Takagi‐Sugeno fuzzy systems under constrained inputs and network delays. Leveraging a hybrid LMI and Secretary Bird Optimization approach, this strategy significantly minimizes communication overhead and computational burden while ensuring optimal reference ...
