We consider nonlinear stochastic wave equations in dimension d\le 3.
Using Malliavin Calculus, we give upper bounds for the small eigenvalues of the inverse of two point densities.These provide a rate of degeneracy when points go close to each other. Then, we analyze the consequences of this result on lower estimates for hitting probabilities.
