چکیده
Abstract In this paper, we study the initial boundary value problem for a class of higher-order n -dimensional nonlinear pseudo-parabolic equations which do not have positive energy and come from soil mechanics, heat conduction, optics. By mountain pass theorem first prove existence nonzero weak solution to static problem, is important basis evolution then based on method potential well global problem.

Boundary Value Problems for Higher Order Parabolic Equations
We consider a constant coefficient parabolic equation of order 2m and establish the existence of solutions to the initial-Dirichlet problem in cylindrical domains. The lateral data is taken from spaces of Whitney arrays which essentially require that the normal derivatives up to order m−1 lie in L2 with respect to surface measure. In addition, a regularity result for the solution is obtained if...

Boundary control for a class of pseudo-parabolic differential equations
The boundary stabilization problem for a class of linear and nonlinear pseudo-parabolic differential equations is considered. The proposed control laws are used to achieve global exponential stability for the linear system and semi-global exponential stability for the nonlinear system in the H 1-sense. An H 2 bound of the solution for the nonlinear system is also derived. A numerical example is...
متن کاملPositive Solutions of a Nonlinear Higher Order Boundary-value Problem
The authors consider the higher order boundary-value problem u(t) = q(t)f(u(t)), 0 ≤ t ≤ 1, u(i−1)(0) = u(n−2)(p) = u(n−1)(1) = 0, 1 ≤ i ≤ n− 2, where n ≥ 4 is an integer, and p ∈ (1/2, 1) is a constant. Sufficient conditions for the existence and nonexistence of positive solutions of this problem are obtained. The main results are illustrated with an example.
