The affine invariant analytic blossom Original Research Article

The definition of the analytic blossom introduced in (Morin and Goldman, 2001) attributes a special role to the value zero. Hans-Peter Seidel (private communication) pointed out that this definition is somehow troublesome, since the underlying domain is affine, and therefore all points in the domain should play the same role. In this short paper, we address this issue and propose a more general definition of the blossom of an analytic function that is not linked with the zero of the coordinate system.
