Abstract: We establish some results in local harmonic analysis which are necessary for Arthur's invariant trace formula for coverings of connected reductive groups. More precisely, for local coverings...
Levinson's theorem and higher degree traces for Aharonov-Bohm operators
Aharonov-Bohm operators scattering theory wave operators index theorem
2011/2/21
We study Levinson type theorems for the family of Aharonov-Bohm models from different
perspectives. The first one is purely analytical involving the explicit calculation of the waveoperators and allo...
Stein's method and the multivariate CLT for traces of powers on the classical compact groups

2010/11/19
Let M be a closed manifold and let CL(M) be the algebra of classical pseudodifferential operators. The aim of this note is to classify trace functionals on the subspaces CL^a(M) of CL(M) of operators...
Prevalence of different double ionization pathways and traces of three-body collisions in strongly driven Helium
double ionization three-body collisions driven Helium
2010/11/16
We present a unified treatment of the prevalence of different double ionization (DI) pathways as a function of the sum of the final electron energies in strongly driven Helium. We do so as a function...
Large Scale Traces of Solar System Cold Dust on CMB Anisotropies

2010/12/24
We explore the microwave anisotropies at large angular scales produced by the emission from cold and large dust grains, expected to exist in the outer parts of the Solar System, using a simple toy mod...
A cellular automaton (CA) is a parallel synchronous computing model, which consists in a juxtaposition of finite automata (cells) whose state evolves according to that of their neighbors. Its trace is...
