摘要

We prove the existence of a global martingale solution of a stochastic electroconvection equations on \({\mathbb {R}}^2\) with multiplicative noise. The proof is based on the stochastic compactness method and the Jakubowski generalization of the Skorokhod theorem. The main difficulty is caused by the nonlinearity term qRq which makes the equations strongly nonlinear.
