Hamilton equations for infinite-dimensional systems, and their variational equations the solutions and first integrals of noncanonical Hamilton equations, their variational equations

Analytic continuation of the Appell function F 1 and integration of the associated system of equations in the logarithmic case corresponding system of partial differential equations are considered in the logarithmic case when

On the existence of solutions to geometrically nonlinear problems for shallow Timoshenko-type shells with free edges of equilibrium equations to one nonlinear differential equation with respect to deflections. In doing so integral

Solvability of one nonlinear boundary-value problem for a system of differential equations of the theory of shallow Timoshenko-type shells of the initial system of equations to one nonlinear operator equation is used to study the problem

Some cases of the solvability in a closed form of singular integral equations and two-dimensional characteristic systemsWe consider the characteristic system of singular integral equations for two unknown functions. We
