Splitting integrators for linear Vlasov equations with stochastic perturbations

Charles-Edouard Bréhier, David Cohen

We consider a class of linear Vlasov partial differential equations driven by Wiener noise. Different types of stochastic perturbations are treated: additive noise, multiplicative…

Positivity-preserving schemes for some nonlinear stochastic PDEs

Charles-Edouard Bréhier, David Cohen, Johan Ulander

We introduce a positivity-preserving numerical scheme for a class of nonlinear stochastic heat equations driven by a purely time-dependent Brownian motion. The construction is insp…

Analysis of a positivity-preserving splitting scheme for some nonlinear stochastic heat equations

Charles-Edouard Bréhier, David Cohen, Johan Ulander

We construct a positivity-preserving Lie--Trotter splitting scheme with finite difference discretization in space for approximating the solutions to a class of nonlinear stochastic…

Uniform error bounds for numerical schemes applied to multiscale SDEs in a Wong-Zakai diffusion approximation regime

Charles-Edouard Bréhier

We study a family of numerical schemes applied to a class of multiscale systems of stochastic differential equations. When the time scale separation parameter vanishes, a well-know…

Uniform strong and weak error estimates for numerical schemes applied to multiscale SDEs in a Smoluchowski-Kramers diffusion approximation regime

Charles-Edouard Bréhier

We study a family of numerical schemes applied to a class of multiscale systems of stochastic differential equations. When the time scale separation parameter vanishes, a well-know…

Splitting schemes for FitzHugh--Nagumo stochastic partial differential equations

Charles-Edouard Bréhier, David Cohen, Giuseppe Giordano

We design and study splitting integrators for the temporal discretization of the stochastic FitzHugh--Nagumo system. This system is a model for signal propagation in nerve cells wh…
