We analyze the most commonly used method for shuffling cards. The
main result is a simple expression for the chance of any arrangement after
any number of shuffles. This is used to give sharp boun...
Constructing a Model Transport Equation for a Massless Bose Gas and its Analytic Solution
massless Bose gas boundary value problem
2011/1/21
A model kinetic equation is constructed for the transport of a massless Bose gas. This equation is applied to solution of the boundary value prob-lem for the transport of radiation in the half-space o...
Sample path deviations of the Wiener and the Ornstein-Uhlenbeck process from its bridges
Sample path deviations Wiener Ornstein-Uhlenbeck process
2010/11/9
We study sample path deviations of the Wiener process from three different representations of its bridge: anticipative version, integral representation and space-time transform. Although these repres...
Convergence in $L^p$ and its exponential rate for a branching process in a random environment
branching process random environment
2010/11/9
We consider a supercritical branching process $(Z_n)$ in a random environment $\xi$. Let $W$ be the limit of the normalized population size $W_n=Z_n/E[Z_n|\xi]$. We first show a necessary and sufficie...
Hilbert schemes of points on a locally planar curve and the Severi strata of its versal deformation
Hilbert schemes of points locally planar curve Severi strata of its versal deformation
2010/11/30
Let C be a locally planar curve. Its versal deformation admits a stratification by the genera of the fibres. The strata are singular; we show that their multiplicities at the central
point are determ...
The persistent cosmic web and its filamentary structure I: Theory and implementation
Cosmology simulations statistics observations Galaxies formation
2010/12/16
We present DisPerSE, a novel approach to the coherent multi-scale identification of all types of astrophysical structures, and in particular the filaments, in the large scale distribution of matter in...
ON A THEOREM OF BERNSTEIN AND ITS APPLICATIONS TO WEIGHTED MINIMAXSERIES
Approximation theory polynomials Bernstein theorem minimax series
2007/12/12
In this paper, some results about approximation in a norm $S$ induced by
the minimax series are studied. Then a Bernstein-type theorem for the
norm $S$ is established. Finally the Bernstein theorem ...
