    Differentiability of the solution operator and the dimension of the attractor for certain power-law fluids

  • Original language description

    We study the dynamics of a two-dimensional homogenenous incompressible fluid of power-law type, with the viscosity behaving like $(1+|Du|)^{p-2}$, $pge2$. Here $Du$ is the symmetric velocity gradient. Thanks to the recent regularity results of Kaplick'y, M'alek and Star'a, we prove that the solution operator is differentiable. This enables us to use the Lyapunov exponents to estimate the dimension of the exponential attractor.

    Diferencovatelnost operátoru řešení a dimenze atraktoru pro jisté polynomiální tekutiny

  • Czech description

    Zabýváme se dynamikou 2d nestlačitelné homogenní tekutiny polynomiálního typu, kde viskozita roste jako $|Du|^{p-2}$, $p>2$ a $Du$ je symetrický gradient rychlosti. Díky nedávným výsledkům o regularitě (Kaplický, Málek, Stará) dokážeme, že operátor řešení je (Fréchetovsky) diferencovatelný. Pomocí Ljapunovských exponentů pak odhadneme dimenzi exponenciálního atraktoru.
