Which elements of a finite group are non-vanishing?
Let $G$ be a finite group. An element $gin G$ is called non-vanishing, if for every irreducible complex character $chi$ of $G$, $chi(g)neq 0$. The bi-Cayley graph ${rm BCay}(G,T)$ of $G$ with respect to a subset $Tsubseteq G$, is an undirected graph with vertex set $Gtimes{1,2}$ and edge set ${{(x,1),(tx,2)}mid xin G, tin T}$. Let ${rm nv}(G)$ be the set of all non-vanishi...
متن کاملCreating effective quality-improvement collaboratives: a multiple case study
OBJECTIVE To explore whether differences between collaboratives with respect to type of topic, type of targets, measures (systems) are also reflected in the degree of effectiveness. STUDY SETTING 182 teams from long-term healthcare organisation developed improvement initiatives in seven quality-improvement collaboratives (QICs) focusing on patient safety and autonomy. STUDY DESIGN Multiple ...
متن کاملRings in which elements are the sum of an idempotent and a regular element
Let R be an associative ring with unity. An element a in R is said to be r-clean if a = e+r, where e is an idempotent and r is a regular (von Neumann) element in R. If every element of R is r-clean, then R is called an r-clean ring. In this paper, we prove that the concepts of clean ring and r-clean ring are equivalent for abelian rings. Further we prove that if 0 and 1 are the only idempotents...

let $g$ be a finite group. an element $gin g$ is called non-vanishing, if for every irreducible complex character $chi$ of $g$, $chi(g)neq 0$. the bi-cayley graph $bcay(g,t)$ of $g$ with respect to a subset $tsubseteq g$, is an undirected graph with vertex set $gtimes{1,2}$ and edge set ${{(x,1),(tx,2)}mid xin g, tin t}$. let $nv(g)$ be the set of all non-vanishing element...
متن کاملWhich presidents are most memorable?
BACKGROUND/RATIONALE Episodic memory loss is a hall-mark of Alzheimer's disease (AD), with recall of recent events becoming progressively difficult. A commonly used tool, the recollection of US presidents, was assessed in evaluating episodic versus semantic memory loss among AD patients compared with spouse controls. METHODS A total of 36 patients (12 men, 24 women) with possible or probable ...
