Abstract
In this paper we consider the stochastic Nizhnik–Novikov–Veselov system, which is forced in the Itô sense by multiplicative noise. To get a new trigonometric and hyperbolic stochastic solutions, we use the tanh–coth method and sine–cosine method. In addition, we demonstrate the effect of multiplicative noise on the exact solutions of the stochastic Nizhnik–Novikov–Veselov system
