DESCRIPTION:Sonja Hohloch (EPFL)\nGeometry and Dynamics SeminarAbstract: I
 n an earlier work with S. Sabatini and D. Sepe\, we studied the transition
  from compact semi-toric systems (i.e. integrable Hamiltonian systems indu
 cing an R x S^1-action) to Hamiltonian S^1-actions by tracking the 5 semi-
 toric invariants introduced by Pelayo & Vu Ngoc and `turning' them in to a
  so-called Karshon-graph (which classifies Haniltonian S^1-spaces).\nIn an
  ongoing work with S. Sabatini\, D. Sepe and M. Symington\, we are studyin
 g the transition from Hamiltonian S^1-spaces to compact semi-toric systems
 \, i.e. how/if/when one can `reverse' the earlier ideas and what new insig
 hts can be gained from Hamiltonian S^1-spaces for semi-toric systems.
