This study investigates two types of one-dimensional stochastic Burgers equations and obtains the probabilities for the occurrence of shocks before and after a given time using different methods. A comparison is made between the Burgers equations with stochastic fluxes and those perturbed by transport noise.
We study two types of one-dimensional stochastic Burgers equations: Burgers equations with stochastic fluxes and Burgers equations perturbed by transport noise. Using the methods of stochastic characteristics and the characteristics perturbed by noise, respectively, we obtain the probabilities for the occurrence of shocks before and after a given time. Compared with the deterministic equations, in case of small initial data the occurrence time of shocks for Burgers equations with stochastic fluxes will be delayed with large probability, but this conclusion is only true for Burgers equations perturbed by the transport noise with large initial data.
