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...

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

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

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...
