Conditions of solvability of the Dirichlet problem for degenerate anisotropic elliptic second-order equations with L¹-data

Kovalevsky, A.A.; Gorban, Yu.S. (Труды Института прикладной математики и механики, 2013)

In this article, we deal with the Dirichlet problem for a class of degenerate anisotropic elliptic second order equations with L¹-right-hand sides in a bounded open set of Rⁿ (n ≥ 2).
Entropy solutions of Dirichlet problem for a class of nonlinear elliptic fourth order equations with L¹-data

Kovalevsky, A.A. (Нелинейные граничные задачи, 1999)

We consider the question on solvability and uniqueness of entropy solutions of Dirichlet problem for a class of nonlinear elliptic fourth order equations with L¹-right-hand sides. We restrict ourselves with equations of ...
Entropy solutions of Dirichlet problem for a class of nonlinear elliptic high-order equations with L¹-data

Kovalevsky, A.A. (Нелинейные граничные задачи, 2002)

In this paper we study Dirichlet problem for nonlinear elliptic high-order equations with coefficients satisfying a strengthened ellipticity condition. A class of nonlinear high-order equations with such a condition on ...
On the Г-compactness of integral functionals with degenerate locally Lipschitz integrands and varying domains of definition

Kovalevsky, A.A.; Rudakova, O.A. (Труды Института прикладной математики и механики, 2012)

In this Note, we announce a new Г-compactness result for a sequence of integral functionals defined on varying weighted Sobolev spaces. The result concerns the case where the degenerate integrands of the functionals satisfy ...
Г-convergence of integral functionals with degenerate integrands in periodically perforated domains

Kovalevsky, A.A.; Rudakova, O.A. (Труды Института прикладной математики и механики, 2009)

We consider a sequence of integral functionals with degenerate integrands in perforated domains of periodic structure. We establish the ¡-convergence of the sequence under consideration to an integral functional defined ...
