A problem with dynamic nonlocal condition for pseudohyperbolic equation
L. S. Pulkina Samara National Research University, 1 Akademika Pavlova str., Samara, 443011 Russia
Abstract:
We consider an initial-boundary problem with dynamic nonlocal boundary condition for a pseudohyperbolic fourth-order equation in a cylinder. Dynamic nonlocal boundary condition represents a relation between values of a required solution, its derivatives with respect of spacial variables, second-order derivatives with respect to time variable and an integral term. The main result lies in substantiation of solvability of this problem. We prove the existence and uniqueness of a generalized solution. The proof is based on the a priori estimates obtained in this paper, Galyorkin's procedure and the properties of the Sobolev spaces.
Keywords:
dynamic boundary conditions, pseudohyperbolic equation, nonlocal conditions, generalized solution.
