Sous-facteurs de L(F∞) d'indice 4cos2π/n,n≥3
No full textLet Q be a factor of type II1, λ a number in the Jones discrete series {4cosπ/m:m≥3}, and {ei} the Jones projections associated with λ. Denote by A2n and A1n the finite-dimensional von Neumann algebras generated, respectively, by {1,e2,⋯,en} and {1,e1,⋯,en}, with the corresponding traces. The author shows that, for n sufficiently large, the index of the inclusion An=(Q⊗A2n)∗A2nA1n⊂(Q⊗A2n+1)∗A2n+1A1n+1=An+1 is equal to λ (here ∗ denotes the reduced, amalgamated free product of the algebras in question). Using the random matrix model of Voiculescu, he proves that if Q is the von Neumann algebra L(F∞) of the free group with infinitely many generators, then An is isomorphic to L(F∞).
The two facts together imply the existence, for any λ in the Jones discrete series, of an irreducible subfactor of L(F∞) of index λ. This constitutes the first example of a nonhyperfinite, non-Γ II1 factor such that its Jones invariant is fully computable (the existence of nonirreducible subfactors of L(F∞) for any index ≥4 is a simple consequence of known results)

Politica e amministrazione, tra etica, managerialità e responsabilità
No full textIl volume raccoglie le versioni, approfondite e rielaborate, delle relazioni discusse in occasione del convegno dal titolo “Politica e amministrazione. Etica, managerialità e responsabilità”, organizzato in onore di Gianfranco D’Alessio. L’oggetto di analisi, la dirigenza amministrativa, è discusso e analizzato, da un lato, in relazione ai principi costituzionali di imparzialità e di buon andamento della Pubblica Amministrazione e, dall’altro, al rapporto che questa instaura con gli organi politici. Il tema è affrontato con approcci variegati e da prospettive molteplici, secondo una impostazione che riflette la pluralità delle competenze e delle esperienze, professionali ed accademiche di ciascun autore.The volume collects the expanded and revised versions of the presentations discussed during the conference titled "Politics and Administration. Ethics, Managerialism, and Accountability," organized in honour of Gianfranco D’Alessio. The focus is on administrative leadership, discussed and analysed from two perspectives. Firstly, in relation to the constitutional principles of impartiality and good administration. Secondly, with reference to the relationship it establishes with political bodies. The topic is approached from various angles and multiple perspectives, reflecting the diversity of skills and experiences, both professional and academic, of each author
A sinfonia do sagrado em Castro Alves: (Deus, Eros e mãe em Os escravos)
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão. Programa de Pós-Graduação em Literatura.No presente trabalho realiza-se uma leitura intertextual entre a Bíblia e Os escravos, coletânea de poemas de teor abolicionista do poeta romântico Antônio Frederico de Castro Alves (1847-1871), objetivando demonstrar que os textos poéticos arquitetam-se na desconstrução e reconstrução dos textos bíblicos. A leitura dos poemas centra-se nos personagens: Deus, Eros e Mãe, os quais conformam uma trindade poética/sagrada. A pesquisa divide-se em três movimentos: Prelúdios do sagrado no Romantismo, Tríade melódica e À guisa de coda: trindade poética. No primeiro efetuam-se algumas aproximações ao conceito do sagrado e aos Romantismos francês e brasileiro. O seguinte corresponde à leitura das composições, através das linhas melódicas: A dualidade de Deus, A ambivalência de Eros e O duplo calvário da Mãe escrava. E no último movimento amalgamam-se as inter-relações entre a trindade cristã e poética e os dramas bíblico e poético

Logarithmic variance profiles and the corresponding f-1 spectra of temperature fluctuations in turbulent Rayleigh-Bénard convection
No full textWe report experimental results for the temperature variance 2(z) and the corresponding frequency spectra P(f) in turbulent Rayleigh-Bénard convection (RBC) in a cylindrical sample of aspect ratioT= D/L = 1:00 (D = 1:12 m is the diameter and L = 1:12 m the height). The measurements were conducted in the Rayleigh-number range 1011 < Ra < 1:35 1014 and Pr ' 0:8. For Ra = 1:35x1014, 2(z) could be described well by a logarithmic dependence on the vertical position z in a range of z 1 < z < z 2 with z 1 ' 70 and z 2 = 0:1L. Here L=(2Nu) is the thickness of a thin thermal sublayer adjacent to the horizontal plate where the heat flux (denoted by the Nusselt number Nu) is carried mostly by thermal diffusion. In the log layer, we found that the temperature spectra had a significant frequency range over which P(f) f with close to 1. As Ra decreased, increased so that the log layer became thinner. At Ra = 2:05 1011, z 2 < z 1 and therefore there was no range for a log layer. Correspondingly, the temperature spectrum near the horizontal plate did not have the f1 scaling form either
