Semi-local invariants for non-resonnant Poisson structures on S1xRn
msra（2004）
摘要
The purpose of this paper is to give a semi-local study along generic closed
curves of zeros: we formally classify Poisson structures defined in a
neighborhood of Gamma:=S^1x{0} in S^1xR^n, that vanish on Gamma, and whose
linear approximation at one point m of Gamma is isomorphic to the dual of a
non-resonant Lie algebra.
