Quantum Coulomb Gases
2011/2/25
Ordinarymatter is composed of electrons (negatively charged) and nuclei (positively charged) interacting via electromagnetic forces. The electric potential between two such particles of charges Q and ...
Alexandrov meets Kirszbraun
Alexandrov Kirszbraun
2011/2/28
We give a simplified proof of the generalized Kirszbraun theorem for Alexandrov spaces, which is due to Lang and Schroeder. We also discuss related questions, both solved and open.
Some Properties of an Infinite Family of Deformations of the Harmonic Oscillator
quantum Hamiltonians superintegrability exchange operators supersymmetry
2011/2/21
In memory of Marcos Moshinsky, who promoted the algebraic study of the har-monic oscillator, some results recently obtained on an infinite family of deformations of such a system are reviewed.
Rigid characterizations of pseudoconvex domains
pseudoconvex domain (weakly) linearly convex domain
2011/3/1
We prove that an open set D in Cn is pseudoconvex if and only if for any z ∈ D the largest balanced domain centered at z and contained in D is pseudoconvex, and consider analogues of that characteriza...
Complete reducibility and Steinberg endomorphisms
G-complete reducibility Steinberg endomorphism Frobenius endomorphism
2011/2/28
Let G be a connected reductive algebraic group defined over an algebraically closed field of positive characteristic. We study a generalization of the notion of G-complete reducibility in the context ...
Periodic orbits of a one dimensional non autonomous Hamiltonian system
Morse theory periodic orbits twisting number
2011/2/28
In this paper we study the properties of the periodic orbits of x + V 0 x(t; x) = 0 with x 2 S1 and V 0 x (t; x) a T0 periodic potential.
Ordinary varieties and the comparison between multiplier ideals and test ideals
Test ideals multiplier ideals ordinary variety semistable reduction
2011/1/21
We consider the following conjecture: if X is a smooth n-dimensional projective variety over a field k of characteristic zero, then there is a dense set of reductions Xs to positive characteristic suc...
Nonassociative strict deformation quantization of C*-algebras and nonassociative torus bundles
Nonassociative strict deformation quantization nonassociative torus bundles T-duality
2011/1/20
In this paper, we initiate the study of nonassociative strict deformation quantization of C-algebras with a torus action. We shall also present a definition of nonassociative principal
torus bundles...
A note on Gornik's perturbation of Khovanov-Rozansky homology
note Gornik's perturbation Khovanov-Rozansky homology
2011/1/21
We show that the information contained in the associated graded vector space to Gornik’s version of Khovanov-Rozansky knot homology is equivalent to a single even integer sn(K). Furthermore we show th...
In this paper we obtain an inequality on the unit disc B in the plane, which improves the classical Moser-Trudinger inequality and the classical Hardy inequality at the same time.
Universality of scaling and multiscaling in turbulent symmetric binary fluids
Universality of scaling turbulent symmetric binary fluids
2010/12/28
We elucidate the universal scaling and multiscaling properties of the nonequilibrium steady states (NESS) in a driven symmetric binary fluid (SBF) mixture in its homogeneous miscible phase in three di...

Considerations about Andrews-Curtis invariants based on sliced 2-complexes.
In this paper we introduce prime fuzzy ideals over a noncommutative ring.This notion of primeness is equivalent to level cuts being crisp prime ideals. It also gener-alizes the one provided by Kumbhoj...
We prove new results on projective normality, normal presentation and higher syzygies for a surface of general type X embedded by adjoint line bundles Lr = K + rB, where B is a base
point free, ample...
