Parabolic Subgroups of Artin Groups [PDF]
Let \((A,\Sigma)\) be an Artin system. For \(X\subseteq\Sigma\) by \(A_X\) is denoted the subgroup of \(A\) generated by \(X\). Such a group is called a parabolic subgroup of \(A\). Van der Lek's theorem is reproved: ``A parabolic subgroup of an Artin group is an Artin group''.

Quasi-permutation Representations of Borel and Parabolic Subgroups of Steinberg's triality groups [PDF]
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 ...

Evaluation of the Floor Acceleration Amplification Demand of Instrumented Buildings
The floor acceleration amplification (FAA) factor is one of the most critical parameters in computing the equivalent seismic force of nonstructural component (NC). To evaluate the heightwise FAA distribution profile, the recorded acceleration response of

Parabolic subgroups of large-type Artin groups
We show that the geometric realisation of the poset of proper parabolic subgroups of a large-type Artin group has a systolic geometry. We use this geometry to show that the set of parabolic subgroups of a large-type Artin group is stable under arbitrary ...

Maximum norm a posteriori error estimation for parabolic problems using elliptic reconstructions [PDF]
A semilinear second-order parabolic equation is considered in a regular and a singularly perturbed regime. For this equation, we give computable a posteriori error estimates in the maximum norm.

The maximal subgroups of the classical groups in dimension 13, 14 and 15 [PDF]
One might easily argue that the Classification of Finite Simple Groups is one of the most important theorems of group theory. Given that any finite group can be deconstructed into its simple composition factors, it is of great importance to have a ...

Conjugacy in relatively extra-large Artin groups [PDF]
Let A be an Artin group with standard generators X={x 1 ,…,x n } , n≥1 and defining graph Γ A . A \emph{standard parabolic subgroup} of A is a subgroup generated by a subset of X .

KOSTANT'S PROBLEM AND PARABOLIC SUBGROUPS [PDF]
AbstractLet be a finite dimensional complex semi-simple Lie algebra with Weyl group W and simple reflections S. For I ⊆ S let I be the corresponding semi-simple subalgebra of . Denote by WI the Weyl group of I and let w○ and wI○ be the longest elements of W and WI, respectively. In this paper we show that the answer to Kostant's problem, i.e.
