On weak solutions of the equations of motion of a viscoelastic medium with variable boundary
Autor: V. P. Orlov, V. G. Zvyagin
Publikováno v: Boundary Value Problems, Vol 2005, Iss 3, Pp 215-245 (2005)
The regularized system of equations for one model of a viscoelastic medium with memory along trajectories of the field of velocities is under consideration. The case of a changing domain is studied. We investigate the weak solvability of an initial b

On the existence of weak solutions for the initial-boundary value problem in the Jeffreys model of motion of a viscoelastic medium
Autor: D. A. Vorotnikov, V. G. Zvyagin
Publikováno v: Abstract and Applied Analysis, Vol 2004, Iss 10, Pp 815-829 (2004)
This paper deals with the initial-boundary value problem for the system of motion equations of an incompressible viscoelastic medium with Jeffreys constitutive law in an arbitrary domain of two-dimensional or three-dimensional space. The existence of

The topological degree method for equations of the Navier-Stokes type
Autor: V. T. Dmitrienko, V. G. Zvyagin
Publikováno v: Abstract and Applied Analysis, Vol 2, Iss 1-2, Pp 1-45 (1997)
We obtain results of existence of weak solutions in the Hopf sense of the initial-boundary value problem for the generalized Navier-Stokes equations containing perturbations of retarded type. The degree theory for maps A−g, where A is invertible an

Flow of electrorheological fluid under conditions of slip on the boundary
Autor: R. H. W. Hoppe, M. Y. Kuzmin, W. G. Litvinov, V. G. Zvyagin
Publikováno v: Abstract and Applied Analysis, Vol 2006 (2006)
We study a mathematical model describing flows of electrorheological fluids. A theorem of existence of a weak solution is proved. For this purpose the approximating-topological method is used.

Optimal feedback control problem for Bingham media motion with periodic boundary conditions
Autor: V. G. Zvyagin, M. V. Turbin
Publikováno v: Доклады Академии наук. 485:139-141
We study the optimal feedback control problem for the motion of Bingham media with periodic boundary conditions in two- and three-dimensional cases. First, the considered problem is interpreted as an operator inclusion with a multivalued right-hand s
