A new numerical scheme for the CIR process

Monte Carlo Methods and Applications, 2015
Abstract In this paper we generalize an explicit numerical scheme for the CIR process that we have proposed before. The advantage of the new proposed scheme is that preserves positivity and is well posed for a (little bit) broader set of parameters among the positivity preserving schemes.

A Numerical Scheme for Evacuation Dynamics

2020
We give a stability condition for a semi–implicit numerical scheme and prove unconditional stability for an implicit scheme for a nonlinear advection – diffusion equation, meant as a model of crowd dynamics. Numerical stability is given for a wider class of equations and schemes.

On Some Properties of KIVA Numerical Schemes

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 1992
AbstractIn this paper numerical schemes of the KIVA code for fluid dynamics modeling will be analyzed. In particular consistency and accuracy will be proved. Attention will be paid to the effects of the grid on the numerical properties of the schemes. Moreover, numerical examples will be given in order to show the actual influence of the choice of the ...
