A pseudospectral scheme for the numerical calculation of shocks

Journal of Computational Physics, 1982
Abstract A pseudospectral numerical scheme is developed in order to calculate the propagation of a shock wave. We use a two-step time-differencing method and a Chebyshev transform method to compute the space derivative. Such a scheme has been used to reduce the oscillations due to Gibb's phenomenon. This numerical method is applied to the solution of

Exact numerical schemes and the three means

International Journal of Computer Mathematics, 1991
Grids based on geometric and harmonic sequences are used here in defining approximations to derivatives which have second order accuracy. Such schemes are superior to the usual arithmetic difference grids for important classes of functions exhibiting significant variation—such as a singularity in a region. Furthermore, the approximations to derivatives

A numerical scheme for a class of sweeping processes

Numerische Mathematik, 2010
The paper deals with a special class of differential inclusions related to perturbed sweeping processes by uniformly prox-regular sets. In the first main part of the paper, the author provides sufficient conditions for the corresponding initial value problems to be well posed in the usual analytical sense.
