Abstract (Feireisl). We show that small perturbations of the spatially
homogeneous equilibrium of a thermally driven compressible viscous fluid
are globally stable. Specifically, any weak solution of the
evolutionary Navier–Stokes–Fourier system driven by thermal convection
converges to an equilibrium as time goes to infinity. The main difficulty
to overcome is the fact the problem does not admit any obvious Lyapunov
function. The result applies, in particular, to the Rayleigh–Benard
convection problem.

Joint work with Yong Lu, Nanjing.

Abstract (Kružík). Non-interpenetration of matter is a well-known challenge
for solid elastic materials combining analytical and geometrical aspects.
In the bulk model, at least on the conceptual level, non-interpenetration
is quite understood even if many challenges still remain open. In
lower-dimensional structures (plates, rods), the situation seems to be even
less clear. Focusing on rods in the plane, we will introduce a possible
concept of noninterpenetration and show density and Gamma-limit results in
this case. This is a joint work in progress with B. Benešová, D. Campbell,
and S. Hencl (all from Prague).
