On eigenelements of a two-dimensional Steklov-type boundary value problem for the Lamé operator

Autor: D.B. Davletov, O.B. Davletov, R.R. Davletova, A.A. Ershov

Publikováno v: Vestnik Udmurtskogo Universiteta. Matematika. Mekhanika. Komp'yuternye Nauki. 33:54-65

In this paper, we study a two-dimensional Steklov-type boundary value problem for the Lamé operator in a half-strip, which is the limiting problem for a singularly perturbed boundary-value problem in a half-strip with a small hole. A theorem on the

On the parametric dependence of the volume of integral funnels and their approximations

Autor: V.N. Ushakov, A.A. Ershov

Publikováno v: Vestnik Udmurtskogo Universiteta. Matematika. Mekhanika. Komp'yuternye Nauki. 32:447-462

We consider a nonlinear control system in a finite-dimensional Euclidean space and on a finite time interval, which depends on a parameter. Reachable sets and integral funnels of a differential inclusion corresponding to a control system containing a

Relationship between α-sets and weakly convex Vial sets

Autor: A.A. Ershov, A.A. Ershova, D.B. Davletov

Publikováno v: VIII Information school of a young scientist Central Scientific Library of the Urals Branch of the Russian Academy of Science.

In the paper, we study properties of the α-sets, which are generalizations of the convex sets. Relationship between the α-sets and weakly convex sets is established. It is proved that the weakly convex Vial sets with bounded Chebyshev radius are α
