Global attractor of a contact parabolic problem in a thin
two-layer domain
A. M. Rekalo, I. D. Chueshov V. N. Karazin Kharkiv National University
Abstract:
A semilinear parabolic equation is considered in the union of two bounded
thin cylindrical domains
$\Omega_{1,\varepsilon}=\Gamma\times(0,\varepsilon)$
and
$\Omega_{2,\varepsilon}=\Gamma\times(-\varepsilon,0)$
adjoining along their bases, where
$\Gamma$ is a domain in $\mathbb R^d$, $d\leqslant3$.
The unknown functions are related by means of an interface condition on
the common base $\Gamma$.
This problem can serve as a reaction-diffusion
model describing the behaviour of a system of two components interacting
at the boundary. The intensity of the reaction is assumed to depend
on $\varepsilon$
and the thickness of the domains, and to be of order $\varepsilon^\alpha$.
Under investigation are the limiting properties of the evolution
semigroup
$S_{\alpha,\varepsilon}(t)$, generated by the original problem as
$\varepsilon\to0$
(that is, as the domain becomes ever thinner).
These properties are shown to depend essentially on the exponent $\alpha$.
Depending on whether $\alpha$ is equal to,
greater than, or smaller than 1, the original system can have three
distinct systems of equations on $\Gamma$
as its asymptotic limit.
The continuity properties of the global attractor of the semigroup
$S_{\alpha,\varepsilon}(t)$ as
$\varepsilon\to0$ are established under natural assumptions.
