We consider the solution x ε of the equation
where W is a Wiener sheet on \(\mathbb{R} \times {\left[ {0;1} \right]}\). In the case where φε 2 converges to pδ(⋅ −a 1) + qδ(⋅ −a 2), i.e., the limit function describing the influence of a random medium is singular at more than one point, we establish the weak convergence of (x ε (u 1,⋅), …, x ε (u d , ⋅)) as ε → 0+ to (X(u 1,⋅), …, X(u d , ⋅)), where X is the Arratia flow.
