The initial boundary-value problem for a nonlinear equation of pseudoparabolic type with nonlinear Neumann boundary condition is considered. We prove a local theorem on the existence of solutions. Using the method of energy inequalities, we obtain sufficient conditions for the blow-up of solutions in a finite time interval and establish upper and lower bounds for the blow-up time.
Mots-clés : Boussinesq equation, pseudoparabolic-type equation
Keywords: initial boundary-value problem, Neumann boundary condition, blow-up of solutions, homogenous isotropic semiconductor, Galerkin's method, dissipative processes in a semiconductor.
