�@The flux conjecture states that the group of Hamiltonian diffeomorphisms is closed
in the symplectomorphism group with respect to 
$C^1$-topology. <BR> 
�@This claim is equivalent to that 
the flux group is closed in the first de Rham cohomology 
group.  I plan to speak about a proof based on Floer-Novikov 
cohomology.
