Permutation statistics on involutions
W. M. B. Dukes
In this paper we look at polynomials arising from statistics on the classes of involutions, , and involutions with no fixed points, , in the symmetric group. Our results…
Wild monodromy and automorphisms of curves
Claus Lehr, Michel Matignon
Let be a complete discrete valuation ring of mixed characteristic with field of fractions containing the -th roots of unity. This paper is concerned with semi-st…
Abundances and ages of the deconvolved thin/thick disks of the Galaxy
Pascal Girard, Caroline Soubiran
We have investigated the abundance of several chemical elements in two large stellar samples kinematically representative of the thin and the thick disks of the Galaxy. Chemical, k…
Equilibrium Onions?
L. Ramos, D. Roux, P. D. Olmsted +1
We demonstrate the possibility of a stable equilibrium multi-lamellar (``onion'') phase in pure lamellar systems (no excess solvent) due to a sufficiently negative Gaussian curvatu…
Scattering theory for the Schrodinger equation with repulsive potential
Jean-Francois Bony, Remi Carles, Dietrich Haefner +1
We consider the scattering theory for the Schrodinger equation with as a reference Hamiltonian, for , in any space dimension. We prove that when this Hamilto…
Recursive graphs with small-world scale-free properties
Francesc Comellas, Guillaume Fertin, André Raspaud
We discuss a category of graphs, recursive clique trees, which have small-world and scale-free properties and allow a fine tuning of the clustering and the power-law exponent of th…
