| Popis: | In this paper, we investigate the stochastic Burgers equation with multiplicative noise defined on the entire real line. The equation can be expressed as follows: $$ \dfrac{\partial u}{\partial t}=\dfrac{\partial^2 u}{\partial x^2}-ku +\dfrac{1}{2}\dfrac{\partial u^2}{\partial x}+\sigma(u)\dfrac{\partial^2 W}{\partial t\partial x}. $$ The noise is characterized as space-time white noise. We establish that the solution remains uniformly bounded in time. Furthermore, by employing the Krylov-Bogolioubov theorem, we establish the existence of invariant measures for this equation. Additionally, we demonstrate the uniqueness of invariant measures by utilizing the strong Feller and irreducible properties. Comment: 24 pages |
