Beale–Kato–Majda type condition for Burgers equation

We consider a multidimensional Burgers equation on the torus T d and the whole space R d . We show that, in case of the torus, there exists a unique global solution in Lebesgue spaces. For a torus we also provide estimates on the large time behaviour of solutions. In the case of R d we establish the existence of a unique global solution if a Beale–Kato–Majda type condition is satisfied. To prove these results we use the probabilistic arguments which seem to be new.
