Quasi-permutation Representations of Borel and Parabolic Subgroups of Steinberg's triality groups [PDF]
Iranian Journal of Numerical Analysis and Optimization, 2009 If G is a finite linear group of degree n, that is, a finite group of automor-phisms of an n-dimensional complex vector space, or equivalently, a finite group of non-singular matrices of order n with complex coefficients, we shall say that G is a quasi ...

Is sleep affected after microgravity and hypergravity exposure? A pilot study. [PDF]
J Sleep ResSummary Sleep is known to be affected in space travel and in residents of the international space station. But little is known about the direct effects of gravity changes on sleep, if other factors, such as sleep conditions, are kept constant. Here, as a first exploration, we investigated sleep before and after exposure to short bouts of microgravity ...

Principal series of Hermitian Lie groups induced from Heisenberg parabolic subgroups [PDF]
Journal of Functional Analysis, 2021 Let G be an irreducible Hermitian Lie group and D = G/K its bounded symmetric domain in C of rank r. Each γ of the Harish-Chandra strongly orthogonal roots {γ1,⋯, γr} defines a Heisenberg parabolic subgroup P = MAN of G.

Type IIB parabolic (p, q)-strings from M2-branes with fluxes
Journal of High Energy Physics, 2023 We extend the work of Schwarz [1] to show that bound states of type IIB supersymmetric (p, q)-strings on a circle are associated with M2-branes irreducibly wrapped on T 2, or equivalently with nontrivial worldvolume fluxes.

The Conjugacy Stability Problem for Parabolic Subgroups in Artin Groups [PDF]
Mediterranean Journal of Mathematics, 2021 Given an Artin group A and a parabolic subgroup P , we study if every two elements of P that are conjugate in A , are also conjugate in P . We provide an algorithm to solve this decision problem if A satisfies three properties that are conjectured to be ...

Representations on Hessenberg Varieties and Young's Rule [PDF]
Discrete Mathematics & Theoretical Computer Science, 2011 We combinatorially construct the complex cohomology (equivariant and ordinary) of a family of algebraic varieties called regular semisimple Hessenberg varieties. This construction is purely in terms of the Bruhat order on the symmetric group. From this a

On the $3$-colorable subgroup $\mathcal{F}$ and maximal subgroups of Thompson's group $F$ [PDF]
, 2021 In his work on representations of Thompson's group $F$, Vaughan Jones defined and studied the $3$-\emph{colorable subgroup} $\mathcal{F}$ of $F$. Later, Ren showed that it is isomorphic with the Brown-Thompson group $F_4$.

Outcome Based Subgroup Analysis: A Neglected Concern. [PDF]
, 2009 A subgroup of clinical trial subjects identified by baseline characteristics is a proper subgroup while a subgroup determined by post randomization events or measures is an improper subgroup.
