Semi-local invariants for non-resonnant Poisson structures on S1xRn
O. Brahic, J. P. Dufour
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…

Veronese curves and webs interpolation
Thomas B. Bouetou, Jean P. Dufour
Veronese webs appear as the natural way of passing to the quotient of curves in the projective space. In thi paper, we give the link between classical multidimensionnal webs and ve…
