Abstract:
We construct an asymptotic (with respect to a small parameter) solution of the Cauchy problem for the perturbed Liouville equation in the case where the unperturbed solution has singularities on timelike lines. We propose a modification of the Krylov–Bogoliubov method that, in particular, allows us to find the asymptotic corrections to the singularity lines.
