Abstract
In this paper, practical stability with respect to a part of the variables of stochastic differential equations driven by G-Brownian motion (G-SDEs) is studied. The analysis of the global practical uniform p th moment exponential stability, as well as the global practical uniform exponential stability with respect to a part of the variables of G-SDEs, is investigated by means of the G-Lyapunov functions. An illustrative example to show the usefulness of the practical stability with respect to a part of the variables notion is also provided.
