SUMMARY:Macarena Peche Irissarry: Reduction of G-ordinary  crystalline repr
 esentations with G-structure
DESCRIPTION:Fontaine’s DcrisDcris functor allows us to associate an isocr
 ystal to any crystalline representation. For a reductive group GG \, we st
 udy the reduction of lattices inside a germ of crystalline representations
  with GG -structure VV to lattices (which are crystals) with GG -structure
  inside Dcris(V)Dcris(V) . Using Kisin modules theory\, we give a descript
 ion of this reduction in terms of GG \, in the case where the representati
 on VV is (GG -)ordinary. In order to do that\, first we need to generalize
  Fargues’ construction of the Harder-Narasimhan filtration for pp -divis
 ible groups to Kisin modules.
