MASALAH EIGEN DAN EIGENMODE MATRIKS ATAS ALJABAR MIN-PLUS

open access: yesBarekeng, 2021
Eigen problems and eigenmode are important components related to square matrices. In max-plus algebra, a square matrix can be represented in the form of a graph called a communication graph.

On the Kantor product, II

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2022
We describe the Kantor square (and Kantor product) of multiplications, extending the classification proposed in [J. Algebra Appl. 2017, 16 (9), 1750167].

Crossed squares of cocommutative Hopf algebras [PDF]

open access: yesJournal of Algebra, 2021
In this paper, we define the notion of Hopf crossed square for cocommutative Hopf algebras extending the notions of crossed squares of groups and of Lie algebras. We prove the equivalence between the category of Hopf crossed squares and the category of double internal groupoids in the category of cocommutative Hopf algebras.

Superboost transitions, refraction memory and super-Lorentz charge algebra [PDF]

open access: yesJournal of High Energy Physics, 2018
A bstractWe derive a closed-form expression of the orbit of Minkowski spacetime under arbitrary Diff(S2) super-Lorentz transformations and supertranslations. Such vacua are labelled by the superboost, superrotation and supertranslation fields.

The singularity category of an algebra with radical square zero [PDF]

open access: yesDocumenta Mathematica, 2011
To an artin algebra with radical square zero, a regular algebra in the sense of von Neumann and a family of invertible bimodules over the regular algebra are associated. These data describe completely, as a triangulated category, the singularity category

B-ORBITS OF SQUARE ZERO IN NILRADICAL OF THE SYMPLECTIC ALGEBRA [PDF]

open access: yes, 2015
Let Sp2n(ℂ) be the symplectic group and (ℂ) its Lie algebra. Let B be a Borel subgroup of Sp2n(ℂ), = Lie(B) and its nilradical. Let be a subvariety of elements of square 0 in : B acts adjointly on .

Concrete–Representational–Abstract (CRA) Instructional Approach in an Algebra I Inclusion Class: Knowledge Retention Versus Students’ Perception

open access: yesEducation Sciences, 2023
Mathematical manipulatives and the concrete–representational–abstract (CRA) instructional approach are common in elementary classrooms, but their use declines significantly by high school.

Quasi-MV algebras for complex fuzzy logic

open access: yesAIMS Mathematics, 2022
Complex fuzzy logic (CFL) is an emerging topic of research in fuzzy logic. Due to the circle structured codomain of the complex membership function, algebraic structure (including MV-algebra) in traditional fuzzy logic cannot be easily transplanted to ...

Mayer–Vietoris squares in algebraic geometry

open access: yesJournal of the London Mathematical Society, 2023
AbstractWe consider various notions of Mayer–Vietoris squares in algebraic geometry. We use these to generalize a number of gluing and push out results of Moret‐Bailly, Ferrand–Raynaud, Joyet and Bhatt. An important intermediate step is Gabber's rigidity theorem for henselian pairs, which our methods give a new proof of.
