Abstract
We are concerned with multidimensional stochastic balance laws We identify a class of nonlinear balance laws for which uniform spatial BV bound for vanishing viscosity approximations can be achieved Moreover we establish temporal equicontinuity in L 1 of the approximations uniformly in the viscosity coefficient Using these estimates we supply a multidimensional existence theory of stochastic entropy solutions In addition we establish an error estimate for the stochastic viscosity method as well as an explicit estimate for the continuous dependence of stochastic entropy solutions on the flux and random source functions Various further generalizations of the results are discussed
