Analytic capacity of sets with plenty of big projections
déc. 2021
Intervenant : Michele Villa
Institution : University of Oulu, Finland
Heure : 14h00 - 15h00
Lieu : Orsay, Bâtiment 307, salle 2L8

An old question, dating back to the sixties and attributed to Vitushkin, asks if, for a compact subset of the plane, analytic capacity is bounded below by Favard length. In this talk, I will describe some ongoing work with D. Dabrowski where we make some progress on this question, at least in the specific case of sets with plenty of big projections.
