Gradings on the algebra of upper triangular matrices and their graded identities

2004

Abstract Let K be an infinite field and let UT n ( K ) denote the algebra of n × n upper triangular matrices over  K . We describe all elementary gradings on this algebra. Further we describe the generators of the ideals of graded polynomial identities of UT n ( K ) and we produce linear bases of the corresponding relatively free graded algebras. We prove that one can distinguish the elementary gradings by their graded identities. We describe bases of the graded polynomial identities in several “typical” cases. Although in these cases we consider elementary gradings by cyclic groups, the same methods serve for elementary gradings by any finite group.

The glocalizing duality of contemporary sport

2010

AbstractThis paper assesses the current debate, in the sphere of the sociology of sport, on globalization and sport, arguing that the advance of world sport now, at the beginning of the twenty-first century, is better understood in terms of the phenomenon of glocalization, that is, as a process by which global demands and forces conform or adapt to local conditions (Robertson), contributing in this way to the production of ‘township’ and ‘community’ and to the emergence of national identities. The 1992 Barcelona Olympics, the 1993 European Football Championship and the 2002 Korea-Japan World Football Cup are presented as examples of the dual and paradoxical character of contemporary sport i…

Inkonsekvent og omskiftelig?

2021

Artikkelen undersøker hvordan historikeren P.A. Munch forholdt seg til idéen om «nordisk» nasjonalitet, og hva han mente om skandinavisme-bevegelsen da den var på sitt mest populære på midten av 1800-tallet. Skandinavismen og tanken om en fellesnordisk nasjonalitet ble aktualisert i forbindelse med de to dansk-tyske krigene i 1848–51 og 1864. Samtidig tok mange aktivt avstand fra bevegelsens ambisiøse program. Ifølge den rådende historieforskningen var den norsk-nasjonale historikeren Munch en av de fremste avstandstagerne, med unntak av en kort periode etter krigsutbruddet i 1848, da han lot seg rive med av idéen og gikk inn for svensk-norsk militærhjelp til Danmark. Denne «skandinavistisk…

Football and National Identities in Spain: The Strange Death of Don Quixote

2020

In spite of its enormous presence and influence on the sport and leisure habits of Spanish society, football has not been a relevant research topic in studies of the social sciences in Spain, excep...

Intersectional scholarship & positive youth development: Post-modern paradigm shift in understanding adjustment of marginalized youth

2016

Research on intersectionality of marginalized youth is generally situated in the assumption that non-normative identity leads to pathology and victimization. Further, most research to date has studied marginalized youth using a traditional nuclear family paradigm. In this paper we discuss how intersectionality addresses the combination of strengths and challenges of living with stigmatizing identities and family processes, towards developing successful youth adjustment. We apply the three-step intersectionality approach to study findings among a group of racial/ethnic minority and sexual minority identified youth and discuss the particular role of familism and extended kinship support belie…

Some characterizations of algebras with involution with polynomial growth of their codimensions

2018

Let A be an associative algebra endowed with an involution ∗ of the first kind and let c ∗n (A) denote the sequence of ∗-codimensions of A. In this paper, we are interested in algebras with involution such that the ∗-codimension sequence is polynomially bounded. We shall prove that A is of this kind if and only if it satisfies the same identities of a finite direct sum of finite dimensional algebras with involution A i , each of which with Jacobson radical of codimension less than or equal to one in A i . We shall also relate the condition of having polynomial codimension growth with the sequence of cocharacters and with the sequence of colengths. Along the way, we shall show that the multi…

Efficient and accurate computation of Green's function for the Poisson equation in rectangular waveguides

2009

[1] In this paper, a new algorithm for the fast and precise computation of Green's function for the 2-D Poisson equation in rectangular waveguides is presented. For this purpose, Green's function is written in terms of Jacobian elliptic functions involving complex arguments. A new algorithm for the fast and accurate evaluation of such Green's function is detailed. The main benefit of this algorithm is successfully shown within the frame of the Boundary Integral Resonant Mode Expansion method, where a substantial reduction of the computational effort related to the evaluation of the cited Green's function is obtained.
