Care tutte, cari tutti,
giovedì 22 Febbraio alle ore 17:00, in Sala Riunioni, per il seminario di Analisi Matematica, avremo il piacere di ascoltare Eduard Feireisl (Institute of Mathematics of the Czech Academy of Sciences), che terrà un seminario dal titolo “Unconditional stability of equilibria in thermally driven compressible fluids”. Trovate qui sotto l’abstract.
Il seminario sarà preceduto da una merenda nella stessa aula, dalle ore 16:30.

A presto,
Ilaria Lucardesi e Luigi Forcella

Dear all,
On Thursday 22nd, February at 5:00 PM, in "Sala Riunioni", for the Mathematical Analysis Seminar, we will have the pleasure of listening to Eduard Feireisl (Institute of Mathematics of the Czech Academy of Sciences). The title of the talk is “Unconditional stability of equilibria in thermally driven compressible fluids”. Please find below the abstract. The seminar will be preceded by a snack in the same room, starting at 4:30 PM.

See you soon,
Ilaria Lucardesi and Luigi Forcella

Title:
Unconditional stability of equilibria in thermally driven compressible fluids

Abstract: 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.
