We consider a model equation of ion-sound waves in ‘non-magnetized’ plasma taking account of non-linear sources localized on the boundary. This generates a non-linear dynamical boundary condition which is ‘close’ to the non-linear Neumann–Dirichlet condition. We prove the existence of a weak generalized solution of this initial-boundary value problem and obtain sufficient conditions for the blow-up of this solution in finite time. We give an upper bound for the time of existence of the solution, which equals its blow-up time. We also obtain sufficient conditions for the existence of a strong generalized solution.
Keywords: blow-up, plasma, ion-sound waves, non-linear boundary conditions.
