Title:Topology and Lipschitz Geometry of Isolated Singularities of Complex Surfaces
Seminar:Center for Dynamics and Geometry Seminars
Speaker:Lev Birbrair, UFC (Fortaleza, Brazil)
Abstract:
We study the question of Bi-Lipschitz Classification of germs of Complex algebraic Surfaces. We are going to present a complete Bi-Lipchitz invariant. This problem is closely related to the topology of 3-folds. The invariant is related to the JSJ-decomposition of the links of the singular points, but not determined by this decomposition. In particular, we will show how one can easily construct that JSJ-decompositions (Carousel of Le Dung Trang). Based on the joint works with Alexandre Fernandes, Walter Neumann and Anne Pichon.
