In this paper we analyze the stronger singularities of solutions $$ u \in H_{\text{loc}}^s(\Omega ),s < \frac{n}{2} $$, for semilinear wave equations, using the microlocal multiplication of the solutions, the fact of the loss in smoothness of the products in Hs, s < n/2, and the trick of reducing the loss in smoothness of the products.
