Speaker: GUILLAUME VALETTE (POLISH ACADEMY OF SCIENCE) Time: 12-1PM, Tuesday, July 26 Room: 707A, Carslaw Lunch: after talk Abstract: it is possible to associate a triangulation to every analytic set, giving information not only on the topology but also on the metric geometry of singularities. The description of the metric geometry provides a much more accurate information (than the description of the topology), valuable for applications. I will introduce these triangulations and give some consequences.
