The local Kostant-PBW ordering
Let \(R\) be a reduced irreducible root system with ordered base \(B\). Let \(\tau\in\Lambda^ +_ r\), the positive cone of the root lattice of \(R\) with respect to \(B\). Konstant's partition function \(P(\tau)\) is the number of ways to write \(\tau\) as a sum of positive roots, and \(E_ +(\tau)\) is the set of such expressions for \(\tau\).

ABSTRACT Amid rising loneliness and declining community participation, service environments have become increasingly important sites of everyday social interaction. Existing research has largely treated Third Place as a property of a space, leaving unexplored how individual customers come to perceive a servicescape as a social home.

Interactions between non-commutative algebraic geometry and skew PBW extensions [PDF]
. We study some relations and interactions between non-commutative algebraic geometry and the skew PBW extensions. For this we will introduce a new class of noncommutative rings, the semi-graded rings, and for them we will prove a generalization of ...

Projective modules and Gröbner bases for skew PBW extensions [PDF]
Many rings and algebras arising in quantum mechanics, algebraic analysis, and non-commutative algebraic geometry can be interpreted as skew PBW (Poincare- Birkhoff Witt) extensions. In the present paper we study two aspects of these non-commutative rings:

Summary Chronic stress, characterized by increased long‐term exposure to the glucocorticoid hormone cortisol, is increasingly linked to obesity development. Still, various knowledge gaps persist, including on underlying pathophysiological mechanisms. The aim of the current review is to provide the latest insights on the connection between stress and ...

PBW deformations arising from algebraic groups
The PBW theorem, named after the authors Poincaré, Birkhoff and Witt, states the following: For a Lie algebra $\mathbb{g}$, the associated graded algebra of its universal enveloping algebra, $\text{gr}~ U(\mathbb{g})$, is isomorphic to its symmetric ...

Propiedad de Armendariz para las extensiones PBW torcidas y su anillo clásico de cocientes
Consideramos un primer acercamiento a la noción de anillo de Armendariz para una extensión torcida de Poincaré-Birkho-Witt (PBW), y su anillo clásico de cocientes.

In recent decades, the effect of human activities on freshwater cycle transgressed the catchment scale. In order to solve the global and regional water problems effectively, a new framework is needed to transform from the traditional hydrology which ...

The oral microbiota and periodontal health in orthodontic patients
Abstract The oral microbiota develops within the first 2 years of childhood and becomes distinct from the parents by 4 years‐of‐age. The oral microbiota plays an important role in the overall health/symbiosis of the individual. Deviations from the state of symbiosis leads to dysbiosis and an increased risk of pathogenicity.
