SUMMARY:Andras Juhasz: \"The sutured Floer homology polytope\"
DESCRIPTION:Abstract: Using sutured Floer homology (in short SFH) I will
  define a polytope inside the second relative cohomology group of a sutu
 red manifold. This is a generalization of the dual Thurston norm polytop
 e of a link-complement studied by Ozsvath and Szabo using link Floer hom
 ology. The polytope is maximal dimensional under certain conditions. Mor
 eover\, surface decompositions correspond to the faces of the polytope i
 n some sense. These imply that if the rank of SFH is < 2^{k+1} then the 
 sutured manifold has a depth at most 2k taut foliation. Moreover\, SFH a
 cts as a complexity for balanced sutured manifolds.
