On invariants for the adjoint action of an unipotent group

Вестник Самарского университета: Естественнонаучная серия
In this paper invariants for the adjoint action of the unitriangular group in the nilradical of a parabolic subalgebra is studied. Consider the adjoint action of the unipotent subgroup U in a parabolic group P, where P = L ⋉ U is the Levi decomposition ...

On the oriented Thompson subgroup F→3 and its relatives in higher Brown–Thompson groups [PDF]

Journal of Algebra and its Applications, 2019
A few years ago the so-called oriented subgroup [Formula: see text] of the Thompson group [Formula: see text] was introduced by V. Jones while investigating the connections between subfactors and conformal field theories. In the coding of links and knots

Density estimates on a parabolic spde [PDF]

, 2002
We consider a general class of parabolic spde's [formula] with (t, x) [member of] [0, T]×[0, 1] and [epsilon]Wt,x, [epsilon] > 0, a perturbed Gaussian space-time white noise.

Parabolic pulse generation through passive reshaping of Gaussian pulses in a normally dispersive fiber [PDF]

, 2007
We numerically and experimentally demonstrate that a Gaussian pulse can be reshaped into a pulse with a stable parabolic intensity profile during propagation in normally dispersive nonlinear ...

Parabolic induction in characteristic p [PDF]

Selecta Mathematica, 2017
Let $$\mathrm{F}$$F (resp. $$\mathbb F$$F) be a nonarchimedean locally compact field with residue characteristic p (resp. a finite field with characteristic p).

Restriction to a parabolic subgroup and irreducibility of degenerate principal series of ${\text{Sp}}\left( {2,\,C} \right)$

, 1970
A series of unitary representations of a semisimple Lie group is said to be a principal series if the representations are induced from characters of a so-called parabolic subgroup.

On rotationally invariant integrable and superintegrable classical systems in magnetic fields with non-subgroup type integrals [PDF]

Journal of Physics A: Mathematical and Theoretical, 2018
The aim of the present article is to construct quadratically integrable three dimensional systems in non-vanishing magnetic fields which possess so-called non-subgroup type integrals.

Normalizers of parabolic subgroups of Coxeter groups [PDF]

Algebraic & Geometric Topology, 2012
We improve a bound of Borcherds on the virtual cohomological dimension of the non-reflection part of the normalizer of a parabolic subgroup of a Coxeter group. Our bound is in terms of the types of the components of the corresponding Coxeter subdiagram rather than the number of nodes.

Convexity of parabolic subgroups in Artin groups [PDF]

Bulletin of the London Mathematical Society, 2014
We prove that any standard parabolic subgroup of any Artin group is convex with respect to the standard generating set.
