Linear Matrix Inequality‐based design of distributed proportional‐integral‐derivative for the output consensus tracking in heterogeneous high‐order multi‐agent systems

Asian Journal of Control, EarlyView.
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

Amenability and coamenability of algebraic quantum groups

International Journal of Mathematics and Mathematical Sciences, 2002
We define concepts of amenability and coamenability for algebraic quantum groups in the sense of Van Daele (1998). We show that coamenability of an algebraic quantum group always implies amenability of its dual.

Twisted automorphisms of group algebras [PDF]

arXiv, 2007
We continue the study of twisted automorphisms of Hopf algebras started in "Twisted automorphisms of Hopf algebras". In this paper we concentrate on the group algebra case. We describe the group of twisted automorphisms of the group algebra of a group of order coprime to 6.

Formulas for the unramified Brauer group of a principal homogeneous space of a linear algebraic group

, 2000
For a smooth compactification V of a principal homogeneous space E under a connected linear algebraic group G defined over a field k of characteristic zero, we present two formulas expressing Br  V /Br  k in terms of G .

Compressibility Function and Speed of Sound in the Non‐Commutative Quantum Hadrodynamics Type‐I Model for Neutron Stars

Astronomische Nachrichten, EarlyView.
ABSTRACT We investigate the effects of a minimal measurable length on neutron stars, within the quantum hadrodynamics (QHD‐I) model modified by the Generalized Uncertainty Principle (GUP). Working in a deformed Poisson algebra framework, we incorporate GUP effects via a time‐invariant transformation of the phase space volume, effectively reducing the ...

Topological Characterizations for Sheaf of the Groups Formed by Topological Generalized Groups

Sakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2019
In the present paper, we providethe some algebraic topologicalcharacterizations for an algebraic sheafby means of the topological generalized group constructed in [3] by consideringboth homotopy and sheaf theory.

Group identities on the units of algebraic algebras with applications to restricted enveloping algebras [PDF]

J. Algebra 319 (2008), no. 10, 4008--4017., 2007
An algebra is called a GI-algebra if its group of units satisfies a group identity. We provide positive support for the following two open problems. 1. Does every algebraic GI-algebra satisfy a polynomial identity? 2. Is every algebraically generated GI-algebra locally finite?

Blend Electrodes in Lithium‐Ion Batteries: Investigation of Inhomogeneities Using a Spatially Resolved Transmission Line Model

Batteries &Supercaps, Accepted Article.
Blend electrodes are used in lithium‐ion batteries to increase the performance by combining two active materials, such as silicon (Si) or silicon oxide (SiOx) and graphite (Gr) for the negative electrode. In‐depth knowledge of the complex interactions between the materials is essential to understand how inhomogeneities and local peaks of the ...

New deformations of Convolution algebras and Fourier algebras on locally compact groups [PDF]

arXiv, 2015
In this paper we introduce a new way of deforming convolution algebras and Fourier algebras on locally compact groups. We demonstrate that this new deformation allows us to reveal some informations of the underlying groups by examinining Banach algebra properties of deformed algebras.

Improving the learning experience in an undergraduate course on microbial metabolism by using an illustrated story

Biochemistry and Molecular Biology Education, Volume 53, Issue 2, Page 131-141, March/April 2025.
Abstract In the classroom, metabolism is often approached and received as a mundane exercise in memorization. Teaching metabolism also faces the challenge of negative perceptions that can impede learning. We sought to improve the learning experience in an undergraduate lecture course on microbial metabolism by implementing an illustrated story that ...
