In this article, we prove uniqueness and energy balance for isentropic Euler system driven by a cylindrical Wiener process. Pathwise result is obtained weak solutions having Hölder regularity C α , > 1 ∕ 2 in space satisfying one-sided Lipschitz bound on velocity. We Onsager’s conjecture with stochastic forcing, that is, equation enjoying 3 . Both the results have been more general setting cons...
