Radiodetection of Cosmic Ray Extensive Air Showers
D. Ardouin, A. Belletoile, D. Charrier +12
We present the characteristics and performance of a demonstration experiment devoted to the observation of ultra high- energy cosmic ray extensive air showers using a radiodetectio…
Generating functions for generating trees
Cyril Banderier, Philippe Flajolet, Daniele Gardy +3
Certain families of combinatorial objects admit recursive descriptions in terms of generating trees: each node of the tree corresponds to an object, and the branch leading to the n…
Polynome de Bernstein-Sato generique local
Rouchdi Bahloul
Given a family of analytic functions near 0 \in C^n parametrized by a smooth space, we study the Bernstein polynomial of the fiber on an irreducible variety V of the space of param…
On subcanonical surfaces of P^4
Ph. Ellia, D. Franco, L. Gruson
We prove that a smooth, subcanonical surface of P^4 (projective space over an algebraically closed field of characteristic zero) is complete intersection if it is contained in a qu…
An iterative-bijective approach to generalizations of Schur's theorem
Sylvie Corteel, Jeremy Lovejoy
We start with a bijective proof of Schur's theorem due to Alladi and Gordon and describe how a particular iteration of it leads to some very general theorems on colored partitions.…
VLTI/VINCI observations of the nucleus of NGC 1068 using the adaptive optics system MACAO
M. Wittkowski, P. Kervella, R. Arsenault +3
We present the first near-infrared K-band long-baseline interferometric measurement of the prototype Seyfert 2 galaxy NGC 1068 with resolution lambda/B \~ 10 mas obtained with the…
