DESCRIPTION:Sonja Hohloch\, EPFL\nIn the first half of the talk\, we will 
 introduce and motivate the concept of Floer homology. Among others\, this 
 includes a discussion of the so-called "Arnold Conjecture" which estimates
  the number of fixed points of a Hamiltonian diffeomorphism by the sum of 
 the Betti numbers of the underlying (closed\, symplectic) manifold.\nAltho
 ugh Floer homology was thought for a long time to be a "symplectic creatur
 e"\, it turned out that it can also be defined (with certain modifications
 ) on certain hyperkahler manifolds. There also exists an hyperkahler analo
 g of the Arnold Conjecture. (This is a joint work with G. Noetzel and D. S
 alamon).\nIn the second half of the talk\, we will study hyperkahler Floer
  homology and "its" Arnold conjecture in more detail\, i.e. we will discus
 s aspects of the proofs and arising new phenomena and problems. If time le
 ft\, we will consider further geometric and dynamical aspects.
