摘要:We study the solvability of a nonlocal problem with integral conditions for a high-order hyperbolic equation with predominant mixed derivative. The posed problem is reduced to the integral equation and the existence of its solution is proved by the help of a priori estimates.

摘要:We consider the Dirichlet problem with nonclassical boundary conditions for a 2nth-order pseudoparabolic equation with nonsmooth coefficients in a rectangular parallelepiped. We prove that this problem is equivalent to the classical Dirichlet problem.

摘要:For a higher-order equation with leading mixed derivative, we consider the Goursat-type problem without consistency conditions. The notion of fundamental solution is introduced. By using this notion, we obtain a representation of the solution of the analyzed problem.

摘要:Abstract(#br)For a higher-order linear hyperbolic equation with nonsmooth coefficients, we consider the Dirichlet and Lidstone problems in a rectangle with nonclassical boundary conditions and prove that these problems are equivalent to the classical Dirichlet and Lidstone proble...

摘要:Abstract(#br)The notion of a control singular with respect to component is introduced and used to propose a new scheme of deriving necessary optimality conditions of the control singular in classical terms with respect to component. New multi-point necessary optimality conditions...

摘要:Abstract(#br)A definition of singular controls with respect to components is given that includes, in particular, the conventional definition. On the basis of this definition, new necessary optimiality conditions for singular controls with respect to components are derived for the...
