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]
Brian Moser caminando por la selva
No full textBrian Moser, vestido con una camisa abierta, pantalón y tenis, camina por la selva amazónica. En su espalda carga una maleta. La fotografía, tomada bajo un ángulo frontal, registra la mirada de Moser en dirección a la cámara. En el fondo se alcanza a observar la vegetación de la región amazónica, debido al plano general de la imagen.
El término 'hupda' se utiliza para designar a uno de los varios grupos seminómadas habitantes del ecosistema transfronterizo amazónico, particularmente el localizado entre Colombia y Brasil. A diferencia de otras comunidades de la zona, los hupda no tuvieron una interacción constante con personas occidentales, debido a su aislamiento geográfico: vivían dentro de la selva y no en las laderas de los ríos (Silverwood-Cope, 1972, p. 30). Es importante mencionar que en el pasado se usaba la palabra 'makú' para denominar a estos pueblos. Sin embargo, al ser un término peyorativo, en la actualidad se prefiere omitir esta designación (Mahecha, Franky y Cabrera, 1996, p. 90).
La serie de fotografías de los hupda registra el viaje exploratorio de Moser por la Amazonía colombiana con el objetivo de grabar el documental War of the Gods (La guerra de los dioses) (1971).Hupd

[hw, pink label]’. Current status. Oplostomus rotundiceps (Moser, 1905), see KRIKKEN (1984). Remark. In our opinion, the date ‘1908’ on the identification label refers to the year during which the specimen was incorporated into Nickerl’s collection. Moser never used preprinted identification labels in his own collection, but often added them to identified specimens deposited in foreign museums.Published as part of Bezděk, Aleš, Hájek, Jiří & Ascr, Biology Centre, 2010, Catalogue of type specimens of beetles (Coleoptera) deposited in the National Museum, Prague, Czech Republic, pp. 629-655 in Acta Entomologica Musei Nationalis Pragae 50 (2) on page 636, DOI: 10.5281/zenodo.532668
