An algebro-geometric construction of lower central series of associative algebras [PDF]

open access: yes, 2013
The lower central series invariants M_k of an associative algebra A are the two-sided ideals generated by k-fold iterated commutators; the M_k provide a filtration of A.

Necessary and sufficient conditions for existence of bound states in a central potential [PDF]

open access: yes, 2003
We obtain, using the Birman-Schwinger method, a series of necessary conditions for the existence of at least one bound state applicable to arbitrary central potentials in the context of nonrelativistic quantum mechanics.

The lower central series of a right-angled Artin group [PDF]

open access: yes, 2011
We give a description of Duchamp and Krob's extension of Magnus' approach to the lower central series of the free group to right-angled Artin groups. We also describe how Lalonde's extension of Lyndon words to the partially-commutative settings gives a ...

Dependent Lindeberg central limit theorem and some applications [PDF]

open access: yes, 2007
In this paper, a very useful lemma (in two versions) is proved: it simplifies notably the essential step to establish a Lindeberg central limit theorem for dependent processes. Then, applying this lemma to weakly dependent processes introduced in Doukhan

Emergency Dynamic Central Venous Cannulation in Preterm Neonates- A Case Series [PDF]

open access: yesJournal of Clinical and Diagnostic Research, 2022
Neonatal venous cannulation is one of the challenges faced by Anaesthesiologists in routine practice. Neonatal cannulation is extremely difficult and time consuming and it has become an inevitable procedure in neonatal intensive care unit, because of ...

On the self-intersections of curves deep in the lower central series of a surface group [PDF]

open access: yes, 2009
We give various estimates of the minimal number of self-intersections of a nontrivial element of the kth term of the lower central series and derived series of the fundamental group of a surface.

Landsat-Based Estimation of Seasonal Water Cover and Change in Arid and Semi-Arid Central Asia (2000–2015)

open access: yesRemote Sensing, 2019
Surface water is of great importance to ecosystems and economies. Crucial to understanding hydrological variability and its relationships to human activities at large scales, open-access satellite datasets and big-data computational methods are now ...

The growth of the maximal term of Dirichlet series

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2018
Let $\Lambda$ be the class of nonnegative sequences $(\lambda_n)$ increasing to $+\infty$, $A\in(-\infty,+\infty]$, $L_A$ be the class of continuous functions increasing to $+\infty$ on $[A_0,A)$, $(\lambda_n)\in\Lambda$, and $F(s)=\sum a_ne^{s\lambda_n}$
