DESCRIPTION:Title: <a href="https://researchseminars.org/talk/NSCM/103/">S
 ome insides in homogenization of compressible Navier-Stokes equations</a>\
 nby Florian Oschmann (Institute of Mathematics AS CR) as part of Nečas Se
 minar on Continuum Mechanics\n\nLecture held in Room K3\,  Faculty of Math
 ematics and Physics\, Charles University\, Sokolovská 83  Prague 8..\n\nA
 bstract\nWe investigate the homogenization of the two- and\nthree-dimensio
 nal unsteady compressible Navier-Stokes equations\, and\nshow (i) the conv
 ergence result for the 2D case\, and (ii) a better lower\nbound for the ad
 iabatic exponent occurring in the pressure law for the\n3D case. The latte
 r will be covered with two different proofs. Lastly\,\nwe briefly discuss 
 the optimality of the achieved bounds for the\nadiabatic exponent in terms
  of the underlying space-time dimension. This\nis joint work with Šárka 
 Nečasová (CAS) and Milan Pokorný\n(Charles University).\n
