Weak convergence of the function-indexed integrated periodogram for infinite variance processes
Weak convergence the function-indexed integrated periodogram
font style='font-size:12px;'>
2010/11/24
In this paper, we study the weak convergence of the integrated periodogram indexed by classes of functions for linear processes with symmetric $\alpha$-stable innovations. Under suitable summability ...
Exponential Convergence to the Maxwell Distribution For Some Class of Boltzmann Equations
Exponential Convergence the Maxwell Distribution
font style='font-size:12px;'>
2010/11/23
We consider a class of nonlinear Boltzmann equations describing return to thermal equilibrium in a gas of colliding particles suspended in a thermal medium. We study solutions in the space $L^{1}(\ma...

Cauchy's condensation test allows to determine the convergence of a monotone series by looking at a weighted subseries that only involves terms of the original series indexed by the powers of two. It ...
Non-convergence of the critical cooling timescale for fragmentation of self-gravitating discs

2010/11/10
We carry out a resolution study on the fragmentation boundary of self-gravitating discs. We perform three-dimensional Smoothed Particle Hydrodynamics simulations of discs to determine whether the crit...
Finite dimensional reduction and convergence to equilibrium for incompressible Smectic-A liquid crystal flows

2010/11/12
The paper considers gossip distributed estimation of a (static) distributed random field (a.k.a., large scale unknown parameter vector) observed by sparsely interconnected sensors, each of which only ...
