Morita homotopy theory for $(\infty,1)$-categories and $\infty$-operads [PDF]

open access: yes, 2019
We prove the existence of Morita model structures on the categories of small simplicial categories, simplicial sets, simplicial operads and dendroidal sets, modelling the Morita homotopy theory of $(\infty,1)$-categories and $\infty$-operads.

Algebraic structures in linear systems theory

open access: yesJournal of Computer and System Sciences, 1970
A new algebraic structure, the R monoid, is associated with a discrete-time, time-invariant linear dynamical system over acommutative ring R, and its properties are investigated.

Highest weight theory for finite-dimensional graded algebras with triangular decomposition [PDF]

open access: yes, 2018
We show that the category of graded modules over a finite-dimensional graded algebra admitting a triangular decomposition can be endowed with the structure of a highest weight category.

On Möbius gyrogroup and Möbius gyrovector space

open access: yesSciPost Physics Proceedings, 2023
Gyrogroups are new algebraic structures that appeared in 1988 in the study of Einstein's velocity addition in the special relativity theory. These new algebraic structures were studied intensively by Abraham Ungar. The first gyrogroup that was considered

Higher algebraic structures in Hamiltonian Floer theory I

open access: yes, 2019
This is the first of two papers devoted to showing how the rich algebraic formalism of Eliashberg-Givental-Hofer's symplectic field theory (SFT) can be used to define higher algebraic structures on the symplectic cohomology of open symplectic manifolds ...

Algebraic structures and lattice properties of hypergraph Pre-Rough sets‎ [PDF]

open access: yesMathematics and Computational Sciences
The study introduces and examines the concept of hypergraph pre-rough sets, which are developed by combining minimum soft descriptions with hypergraph structures.

Cohomology and extensions of braces [PDF]

open access: yes, 2016
Braces and linear cycle sets are algebraic structures playing a major role in the classification of involutive set-theoretic solutions to the Yang-Baxter equation. This paper introduces two versions of their (co)homology theories.

Some Innovative Types of Fuzzy Ideals in AG-Groupoids

open access: yesJournal of Intelligent Systems, 2019
AG-groupoids (non-associative structure) are basic structures in Flocks theory. This theory mainly focuses on distance optimization, motion replication, and leadership maintenance with a wide range of applications in physics and biology.

Petrographic structures and Hardy – Weinberg equilibrium

open access: yesЗаписки Горного института, 2020
The article is devoted to the most narrative side of modern petrography – the definition, classification and nomenclature of petrographic structures. We suggest a mathematical formalism using the theory of quadratic forms (with a promising extension to ...
