Quantum groups, Yang–Baxter maps and quasi-determinants
For any quasi-triangular Hopf algebra, there exists the universal R-matrix, which satisfies the Yang–Baxter equation. It is known that the adjoint action of the universal R-matrix on the elements of the tensor square of the algebra constitutes a quantum ...

We consider fuzzy sets and generalized triangular norms on positive elements of order commutative C ∗ $C^{*}$ -algebras to study the concept of C ∗ $C^{*}$ -algebra valued normed algebras with uncertainty.

The structure of graded triangular algebras T of arbitrary dimension are studied in this paper. This is motivated in part for the important role that triangular algebras play in the study of oriented graphs, upper triangular matrix algebras or nest algebras.

On Jordan centralizers of triangular algebras [PDF]
Let A be a unital algebra over a number field F. A linear mapping ϕ from A into itself is called a Jordan-centralized mapping at a given point G∈A if ϕ(AB+BA)=ϕ(A)B+ϕ(B)A=Aϕ(B)+Bϕ(A) for all A, B∈A with AB=G. In this paper, it is proved that each Jordan-centralized mapping at a given point of triangular algebras is a centralizer. These results are then

Localized and Extended Phases in Square Moiré Patterns
Rotated superimposed lattices in two dimensions, the termed moiré patterns, represent a clear example of how the structure affects the physical properties of a particle moving on it. A robust numerical treatment of continuous and discrete models leads to confirm that while localized states result from angles that produce non‐commensurable lattices ...

Efficient modelling of natural gas pipeline on electromagnetic transient simulation programs
Abstract Electromagnetic transient programs (EMTPs) are widely used for simulating electromagnetic transient in power systems. With the increasing interest in integrated energy system (IES), it would be beneficial to extend the scope of EMTP‐type application to multi‐physics transients in integrated electrical and gas networks.

Abstract This article addresses the cooperative output consensus tracking problem for high‐order heterogeneous multi‐agent systems via a distributed proportional‐integral‐derivative (PID)‐like control strategy and proposes two novel control methodologies for the tuning of the control gains, which do not require any assumption and/or limitation on agent

This research work explains a sliding mode controller‐based multilevel inverter for grid integrated photovoltaic (PV) power structure. A gravitational search algorithm (GSA) based on maximum power point tracking (MPPT) has also been discussed for optimal PV power achievement.

The image of polynomials in one variable on 2×2 upper triangular matrix algebras
In the present paper, we give a description of the image of polynomials in one variable on 2×2 upper triangular matrix algebras over an algebraically closed field.
