Ciclo di Seminari - Progetto ERC PASCAL (Probabilistic and Statistical Techniques for Cosmological Applications) Lunedì 7 aprile ore 14 Aula D'Antoni 1101 Dipartimento di Matematica Università di Roma Tor Vergata Speaker: Jean-Marc Azaïs IMT, Universite de Toulouse, France Title: The tail of the maxima  of Gaussian fields on non locally convex sets. Abstract: The Euler Characteristic method or  the Rice method  give a full expansion of the tail of the maximum of stationary Gaussian fields  defined on some regular sets.   A key hypothesis  is local convexity  that means roughly  that, by a smooth  change of parameterization,   the parameter set can be transform  in a convex set.   In our talk we will present   an alternative method that works   for general parameter set as fractals sets  and permits to obtain a full expansion  in  dimensions 2 for a large class.   Our result will be  illustrated by  examples that are all new. Tutti gli interessati sono invitati a partecipare. ................................................................................
