Symmetry and Perturbation Theory 2011


The conference Symmetry and Perturbation Theory 2011 took place last week in Otranto. The conference was organized by Giuseppe Gaeta, Ferdinand Verhulst, Raffaele Vitolo, and Sebastian Walcher.

In the conference I gave an invited talk with title «Uncovering fractional monodromy» presenting a work I am doing in collaboration with Henk Broer. The main idea behind this work is that when dealing with systems that have fractional monodromy it is more natural to first lift them to a branched covering space. Such lift simplifies the geometry of the fibers and allows a straightforward description of the global geometry. Pushing this description down to the original space reveals the fractional monodromy.
