This leads to an observability estimate for stochastic wave equations with non-smooth lower order terms. Moreover, the observability constant is estimated by an explicit function of the norm of the involved coefficients in the equation.12 pagesAnalysis of PDEsOptimization and Control35B45; 93B07text
