DESCRIPTION:I will begin with a quick intro to Hamiltonian group actions i
 n symplectic geometry\, in particular symplectic 6-manifolds with a Hamilt
 onian circle action. By results of Tolman and McDuff there are only 4 exam
 ples with second Betti number equal to 1. I will discuss a conjectural des
 cription of Hamiltonian circle actions on 6-manifolds that are “Fano” 
 in the sense that the cohomology class of the symplectic form is a positiv
 e multiple of the first Chern class.
