2011/9/8
If our mind is just an algorithm running on a flesh hardware, then it seems that there is no place for the free-will. An algorithm decides everything based on deterministic computations, or on random ...

Convergence order of a numerical scheme for sweeping process
Differential inclusions Subdifferential calculus Numerical analysis Predictioncorrection
font style='font-size:12px;'>
2010/12/6
In this paper, we show that the convergence order of the numerical scheme introduced in [12] for sweeping processes is equal to one. The considered differential inclusions involve a set-valued map, gi...
Stochastic Shear Thickening Fluids:Strong Convergence of the Galerkin Approximation and the Energy Equality
Stochastic Shear Thickening Fluids:Strong Convergence Galerkin Approximation Energy Equality

2010/12/3
We consider a SPDE (stochastic partial differential equation) which describes the velocity field of a viscous, incompressible non-Newtonian fluid subject to a random force.Here, the extra stress tenso...
Numerical Feynman integrals for density operator dynamics using more than one mesh: faster convergence and significant reduction of computational cost
Feynman integral path integral QUAPI Feynman-Vernon
font style='font-size:12px;'>
2010/10/26
The Feynman integral is one of the most accurate methods for calculating density operator dy-
namics in open quantum systems. However, the number of time steps that can realistically be used is alway...
Surface measures and convergence of the Ornstein-Uhlenbeck semigroup in Wiener spaces
Surface measures convergence of the Ornstein-Uhlenbeck semigroup Wiener spaces

2010/11/26
We study points of density 1/2 of sets of finite perimeter in infinite-dimensional Gaussian spaces and prove that, as in the finite-dimensional theory, the surface measure is concentrated on this clas...

2010/11/26
We extend to Lipschitz continuous functionals either of the true paths or of the Euler scheme with decreasing step of a wide class of Brownian ergodic diffusions, the Central Limit Theorems formally e...
Self-Similarity and Lamperti Convergence for Families of Stochastic Processes
fractional Hougaard motion Hougaard L´ evy process Lamperti Lamperti
font style='font-size:12px;'>
2010/11/26
We define a new type of self-similarity for one-parameter families of stochastic processes,
which applies to a number of important families of processes that are not self-similar in the
conventional...
