Factorization in generalized Calogero-Moser spaces
No full textUsing a recent construction of Bezrukavnikov and Etingof we prove that there is a factorization of the Etingof-Ginzburg sheaf on the generalized Calogero-Moser space associated to a complex reflection group. In the case W = S_n, this confirms a conjecture of Etingof and Ginzburg
On singular Calogero-Moser spaces
No full textUsing combinatorial properties of complex reflection groups, we show that the generalised Calogero-Moser space associated to the centre of the corresponding rational Cherednik algebra is singular for all values of its deformation parameter c if and only if the group is different from the wreath product and the binary tetrahedral group. This result and a theorem of Ginzburg and Kaledin imply that there does not exist a symplectic resolution of the singular symplectic variety h+h*/W outside of these cases; conversely we show that there exists a symplectic resolution for the binary tetrahedral group (Hilbert schemes provide resolutions for the wreath product case)
Sign-changing blow-up for the Moser–Trudinger equation
No full textGiven a sufficiently symmetric domain Ω⋐R2, for any k∈N∖{0} and β>4πk we construct blowing-up solutions (uε)⊂H01(Ω) to the Moser–Trudinger equation such that as ε↓0, we have ‖∇uε‖Ljavax.xml.bind.JAXBElement@57b4bd332→β, uε⇀u0 in H01 where u0 is a sign-changing solution of the Moser–Trudinger equation and uε develops k positive spherical bubbles, all concentrating at 0∈Ω. These 3 features (lack of quantization, non-zero weak limit and bubble clustering) stand in sharp contrast to the positive case (uε>0) studied by the second author and Druet [8]

Spéciation chez le Pulsatilla alpina (L.) Delarbre dans le domaine alpin
No full textIm Alpenraum wurden zwei neue Unterarten der Pulsatilla alpina (L.) Delarbre neu beschrieben: P. alpina subsp. austroalpina D. M. Moser und P alpina subsp. schneebergensis D. M. Moser. Zwei neue Kombinationen wurden gültig veröffentlicht: P. alpina subsp. collianaea (Beauverd) D. M. Moser und P. alpina subsp. millefoliata (Bertol.) D. M. Moser. Es handelt sich um geographisch isolierte Sippen. Pulsatilla alpina subsp. austroalpina wächst in den Bergamasker- und Judikarischen Alpen, den Dolomiten, den Karawanken und in den Julisehen Alpen. Pulsatilla alpina subsp. cottianaea existiert in einem kleinen Areal in den Cottischen Alpen, am Passo Moncenisio. Pulsatilla alpina subsp. millefoliata besitzt ein grösseres Verbreitungsgebiet in den Westalpen, in den Grajischen und in den Seealpen und wächst ferner noch im Apennin. Pulsatilla alpina subsp. schneebergensis besiedelt die nordöstlichen Kalkalpen von Österreich und ist vom Wiener Schneeberg beschrieben. Die vier Unterarten wurden mit den bereits im Alpenraum bestehenden Sippen, P. alpina (L.) Delarbre subsp. alpina, P. alpina subsp. apiifolia (Scop.) Nyman, und P. alpina subsp. austriaca Aichele & Schwegler biosystematisch verglichen.Two new and geographically isolated subspecies of Pulsatilla alpina (L.) Delarbre are described for the Alps: P. alpina subsp. austroalpina D. M. Moser and P. alpina subsp. schneebergensis D. M. Moser. Two new combinations are validated: P alpina subsp. cottianaea (Beauverd) D. M. Moser and P. alpina subsp. millefoliata (Bertol.) D. M. Moser. Pulsatilla alpina subsp. austroalpina grows in the Bergamese and Giudicarie Alps, the Dolomites, the Karawanken range and in the Julian Alps. Pulsatilla alpina subsp. cottianaea is found in a restricted area of the Cottian Alps, at the foot of Passo Moncenisio. Pulsatilla alpina subsp. millefoliata has a wider distribution and is found in the western Alps, the Graian Alps, the Maritime Alps and is also found in the Apennine. Pulsatilla alpina subsp. schneebergensis is described from the Schneeberg near Vienna and colonizes the northeastern ranges of the Austrian Alps, the Kalkalpen. Using biosystematic methods, these four subspecies are compared to the taxa already known from the Alps, P alpina (L.) Delarbre subsp. alpina, P alpina subsp. apiifolia (Scop.) Nyman, P alpina subsp. austriaca Aichele Schwegler.Deux nouvelles sous-espèces du Pulsatilla alpina (L.) Delarbre sont décrites dans le domaine alpin: P. alpina subsp. austroalpina D. M. Moser et P. alpina subsp. schneebergensis D. M. Moser. Deux combinaisons nouvelles sont, d'autre part, établies: P. alpina subsp. cottianaea (Beauverd) D. M. Moser et P. alpina subsp. millefoliata (Bertol.) D. M. Moser. II s'agit de taxons isolés du point de vue géographique. Le P. alpina subsp. austroalpina prospère dans les Alpes bergamasques et de Giudicarie, dans les Dolomites, les Karawanken et les Alpes juliennes. Le P. alpina subsp. cottianaea montre une petite aire de distribution dans les Alpes cottiennes, au col du Mont Cenis . L'aire du P. alpina subsp. millefoliata est plus étendue dans les Alpes occidentales, des Alpes graies aux Alpes maritimes; cette sous-espèce se rencontre aussi sur I 'Apennin. Le P. alpina subsp. schneebergensis est une plante des Alpes calcaires au nord-est de I 'Autriche; elle est décrite du Schneeberg. D ' un point de vue biosystématique, ces quatre sous-espèces sont comparées avec celles déjà connues dans le domaine alpin, à savoir: le P. alpina subsp. alpina, le P. alpina subsp. apiifolia (Scop.) Nyman et le P. alpina subsp. austriaca Aichele & Schwegler

Contributions of machine learning to remote sensing data analysis
No full textThis article describes the state of the art on the development and application of machine learning methodologies in the remote sensing domain. In an introductory section, we describe the specific remote sensing analysis problems that are typically handled by machine learning. The remaining of the article is subdivided in a number of sections, dealing with groups of machine learning strategies. The following strategies are elaborated on: kernel methods, neural network methods, manifold learning methods, structured output methods, ensemble learning methods, and sparse learning methods. This specific choice is based on the frequency with which these strategies appeared in the recent remote sensing literature. Each subsection contains a short description of the specific machine learning paradigm and an extensive description of the recent state of the art, with a conceptual description of the new methodologies. We end with some insights in future developments.</p

The unique known female of <i>D. riograndensis</i> differs from the female of <i>D. sombrero</i> by its smaller wingspan (96 mm in <i>D. sombrero</i> (Miranda <i>et al</i>. 2015)) and for the FW postmedial line being slightly concave (bent inward in <i>D. sombrero</i> at CuA 1).
