Espaces de représentations complètement réductibles
We study some geometric properties of actions on nonpositively curved spaces related to complete reducibility and semisimplicity, focusing on representations of a finitely generated group Γ in the group G of rational points of a reductive group over a local field, acting on the associated space (symmetric space or affine building). We prove that the space of completely reducible classes is the ...
متن کاملL’involution De Zelevinski Modulo
Let F be a non-Archimedean locally compact field with residual characteristic p, let G be an inner form of GLn(F), n 1 and let R be an algebraically closed field of characteristic different from p. When R has characteristic > 0, the image of an irreducible smooth R-representation π of G by the Aubert involution need not be irreducible. We prove that this image (in the Grothendieck group of G) c...
متن کاملReprésentations et régularisations pour la classification de sentiments
As web 2.0 is spreading, users get used to give their opinion on forums, blogs and e-commerce websites. This is a valuable piece of information for many applications such as consumer modeling, sales prediction or opinion survey. According to the literature, the efficiency of opinion mining tools will mainly relies on the ability of discriminating texts that express positive sentiments from text...
متن کاملIntégration de plusieurs formes de représentations spatiales dans un modèle de simulation
Résumé. L’étude de l’évolution d’un système complexe spatialisé devient critique dans de nombreux domaines. Par exemple, pour comprendre l’influence de l’homme sur le ruissellement dans les entités spatiales et selon leurs types d’occupation du sol (culture, urbanisation, habitation...) de manière à permettre aux décideurs d’anticiper les politiques d’urbanisme et d’agriculture. Dans cette démo...
متن کاملReprésentations d ’ images pour la reconnaissance de formes
One of the main requirements in many signal processing applications is to have a “meaningful representation” in which signal’s characteristics are readily apparent. For example, for recognition, the representation should highlight salient features; for denoising, it should efficiently separate signal and noise; and for compression, it should capture a large part of signal using only a few coeff...
