Nonlinear stability issues for stochastic Runge-Kutta methods

The paper provides a nonlinear stability analysis for a class of stochastic Runge-Kutta methods, applied to problems generating mean-square contractive solutions. In particular, we show how this property is inherited along the solutions generated by the stochastic perturbation of an algebraically stable deterministic Runge-Kutta method. The effectiveness of the results is also confirmed by selected numerical experiments.
