Degenerate Series Representations of the q-Deformed Algebra $so'_q(r,s)$

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2007
The $q$-deformed algebra ${m so}'_q(r,s)$ is a realform of the $q$-deformed algebra $U'_q({m so}(n,mathbb{C}))$,$n=r+s$, which dif/fers from the quantum algebra $U_q({mso}(n,mathbb{C}))$ of Drinfeld and Jimbo.

Generation of Basis Vectors for Magnetic Structures and Displacement Modes

open access: yesAdvances in Condensed Matter Physics, 2016
Increasing attention is being focused on the use of symmetry-adapted functions to describe magnetic structures, structural distortions, and incommensurate crystallography.

Connections with Irreducible Holonomy Representations

open access: yesAdvances in Mathematics, 2001
A subgroup of a linear group is called a Berger group if it satisfies all algebraic conditions for being the holonomy group of a torsion free affine connection. These conditions were introduced by Berger who also produced the list of such groups. Famous problems of differential geometry were to establish which groups from this list are realized by the ...

3D Topological Inorganic Electrides: Screening, Properties, and Applications

open access: yesAdvanced Science, EarlyView.
In inorganic electrides, zero‐, one‐, and two‐dimensional (0D, 1D, and 2D) interstitial anionic electrons interconnect within lattice cavities, collectively forming a three‐dimensional (3D) network, further coupling magnetism and topological features, leading to the emergence of 3D topological inorganic electrides.

Varieties of four-dimensional gauge theories

open access: yesJournal of High Energy Physics
We use algebraic geometry to study the anomaly-free representations of an arbitrary gauge Lie algebra for 4-dimensional spacetime fermions. For irreducible representations, the problem reduces to studying the Lie algebras 𝔰𝔲 n for n ≥ 3.

Tensor products of irreducible projective integer 2-adic representatione of cyclic 2-group

open access: yesНауковий вісник Ужгородського університету. Серія: Математика і інформатика, 2017
The paper deals with a subalgebra of the algebra of projective integer 2-adic images of a cyclic 2-group, generated by irreducible projective integers of 2-adic representations.

The Irreducible Representations of the Hecke Category

open access: yesJournal of Algebra, 1999
The Iwahori-Hecke algebra (or \(A_n\)-series Hecke algebra) is defined as the quotient of the group algebra of the (\(A_n\)-type) braid group by the quadratic relations \((\sigma_i-1)(\sigma_i+q)=0\), where \(\sigma_i\) (\(1\leq i\leq n-1\)) are the standard symmetric group generators, reducing to the group algebra of the symmetric group at \(q=1 ...

Orthogonality Relations and Supercharacter Formulas of U(m|n) Representations

open access: yes, 1997
In this paper we obtain the orthogonality relations for the supergroup U(m|n), which are remarkably different from the ones for the U(N) case. We extend our results for ordinary representations, obtained some time ago, to the case of complex conjugated ...

What matters for agricultural trade? Assessing the role of trade deal provisions using machine learning

open access: yesApplied Economic Perspectives and Policy, EarlyView.
Abstract This paper employs machine learning to determine which preferential trade agreement (PTA) provisions are relevant to agricultural trade patterns and the factors that may influence their adoption. Utilizing the three‐way gravity model, we apply plug‐in Lasso regularized regression to pinpoint predictive PTA provisions for agricultural trade ...

Modulo $p$ parabolic induction of pro-$p$-Iwahori Hecke algebra [PDF]

open access: yes, 2015
We study the structure of parabolic inductions of a pro-$p$-Iwahori Hecke algebra. In particular, we give a classification of irreducible modulo $p$ representations of pro-$p$-Iwahori Hecke algebra in terms of supersingular representations.
