On the initial boundary value problem for a nonlinear nonhomogeneous equation of Sobolev type
A. I. Aristov Faculty of Computational Mathematics and Cybernetics, Moscow State University, Moscow, Russia
Abstract:
The initial boundary value problem for a nonlinear nonhomogeneous equation of Sobolev type used for modeling nonstationary processes in semiconductors is examined. It is proved that this problem is uniquely solvable at least locally in time. Sufficient conditions for the problem to be solvable globally in time are found, as well as sufficient conditions for the local (but not global) solvability. In the case of only local solvability, upper and lower estimates for the time when a solution exists are determined in the form of either explicit or quadrature formulas.
Key words:
initial boundary value problem for an equation of Sobolev type, conditions for the destruction of solutions, method of energy estimates.
