DESCRIPTION:Title: <a href="https://researchseminars.org/talk/NSCM/220/">V
 ariational homogenization of some nonlinear Stokes problem</a>\nby Edoardo
  Tolotti (University of Münster) as part of Nečas Seminar on Continuum M
 echanics\n\nLecture held in Room K3\,  Faculty of Mathematics and Physics\
 , Charles University\, Sokolovská 83  Prague 8..\n\nAbstract\nIn this tal
 k I will present the current progress of an ongoing joint project with R. 
 Höfer and C. Zeppieri. We study the homogenization of nonlinear Stokes-ty
 pe problems for incompressible fluids on randomly perforated domains. We a
 ssume minimal hypotheses on the obstacles distribution\, allowing for clus
 tering and overlapping of perforations. By means of a Γ-convergence resul
 t\, we show that\, similarly to the case of nonlinear Laplace problems\, t
 here is a critical scale of the obstacles for which an extra term appears 
 in the limiting energy. This extra term may be interpreted as an effective
  drag term due to the homogenized presence of perforations.\n
