Propagation of singularities for generalized solutions to nonlinear wave equations
Hideo Deguchi, Michael Oberguggenberger
The paper is devoted to regularity theory of generalized solutions to semilinear wave equations with a small nonlinearity. The setting is the one of Colombeau algebras of generaliz…
