Singularities and bifurcations of 3-dimensional Poisson structure
J. -P. Dufour, M. Zhitomirskii
Abstract
We give a normal form for families of 3-dimensional Poisson structures. This allows us to classify singularities with nonzero 1-jet and typical bifurcations. The Appendix contains corollaries on classification of families of integrable 1-forms on $R3
