Irreducible representations of E theory [PDF]

International Journal of Modern Physics A, 2019
We construct the [Formula: see text] theory analogue of the particles that transform under the Poincaré group, that is, the irreducible representations of the semi-direct product of the Cartan involution subalgebra of [Formula: see text] with its vector representation. We show that one such irreducible representation has only the degrees of freedom of

Irreducible representations of Leavitt algebras

Journal of Algebra, 2022
For a weighted graph $E$, we construct representation graphs $F$, and consequently, $L_K(E)$-modules $V_F$, where $L_K(E)$ is the Leavitt path algebra associated to $E$, with coefficients in a field $K$. We characterise representation graphs $F$ such that $V_F$ are simple $L_K(E)$-modules.

On irreducible projective representations of finite groups [PDF]

Surveys in Mathematics and its Applications, 2009
The paper is a survey type article inwhich we present some results on irreducible projective representations offinite groups. Section 2 includes Curtis and Reiner's theorem inwhich is proved that a finite group has at most a finite number ofinequivalent ...

2D Multifunctional Spin‐Orbit Coupled Dirac Nodal Line Materials

Advanced Functional Materials, EarlyView.
A total of 473 nonmagnetic and antiferromagnetic 2D spin‐orbit coupled Dirac nodal line materials are screened, spanning 5 layer groups and 12 magnetic space groups. Furthermore, it integrates their topological properties with electride, multiferroic, and magnetic characteristics, revealing unique systems with expanded functionalities and promising ...

Representations of 3-Dimensional Simple Multiplicative Hom-Lie Algebras

Advances in Mathematical Physics, 2013
The aim of this paper is to study representations of 3-dimensional simple multiplicative Hom-Lie algebras (whose structure is of A1-type). In this paper we can see that a finite dimensional representation of is not always completely reducible, and a ...

Irreducible representations of normal spaces [PDF]

Proceedings of the American Mathematical Society, 1989
We define the notion of irreducible polyhedral representation of a normal space making use of approximate inverse systems. This generalizes the concept of irreducible polyhedral expansions introduced in 1937 by Freudenthal for metric compacta and generalized to uniform spaces by Isbell in 1961.

Anomalous Phonon Softening with Inherent Strain in Wrinkled Monolayer WSe2

Advanced Materials, EarlyView.
This study introduces the first discovery of a new local strain indicator, A2′′(Γ)$A_2^{^{\prime\prime}}( \Gamma )$ mode, for monolayer WSe2‐based excitonic applications including single photon emitter by using tip‐enhanced Raman spectroscopy. The correlative investigation with density functional perturbation theory provides the origin of the anomalous

The Khovanov-Lauda 2-Category and Categorifications of a Level Two Quantum SL(N) Representation

International Journal of Mathematics and Mathematical Sciences, 2010
We construct 2-functors from a 2-category categorifying quantum sl(n) to 2-categories categorifying the irreducible representation of highest weight 2ωk.

Electric‐Field‐Driven Reversal of Ferromagnetism in (110)‐Oriented, Single Phase, Multiferroic Co‐Substituted BiFeO3 Thin Films

Advanced Materials, Volume 37, Issue 29, July 24, 2025.
Electric‐field‐induced magnetization reversal is a long‐sought‐after achievement in materials engineering for use in next‐generation, ultra‐low power consumption memory devices. This work demonstrates fully electric‐field‐driven switching of the out‐of‐plane component of magnetization in (110)‐oriented Co‐substituted BiFeO3 thin films at room ...

Groups having unique faithful irreducible Q-representation

Ratio Mathematica
In this paper, we give few sufficient conditions for finite p-group to have unique NEW (i.e faithful irreducible) Q-representation. As a consequence of these conditions we will prove that any finite p-group of nilpotency class 2 has atmost one NEW Q ...
