Dear All:

Next Wednesday, Anna Vidotto (Università degli Studi di Napoli Federico II) will give a seminar talk on the Excursion Area of Time Dependent Spherical Random Fields, which will be held in person and online via Zoom.

* Place: room 2AB40 at the Department of Mathematics, University of Padua
(Torre Archimede, via Trieste, 63, 35121 Padova)

* Zoom link: please visit the webpage https://www.math.unipd.it/~bianchi/seminari/

* Title: On the Excursion Area of Time Dependent Spherical Random Fields

* Abstract: In this talk, we consider isotropic and stationary real Gaussian time dependent random fields defined on the two dimensional unit sphere S^2 and we investigate the asymptotic behavior, as T tends to infinity , of the excursion area in S^2 × [0, T] at any threshold, covering both cases when the field exhibits short and long memory, that is, integrable and non-integrable temporal covariance. It turns out that the limiting distribution is not universal, depending both on the memory parameters and the threshold. The talk is based on a joint work with D. Marinucci and M. Rossi.

On behalf of the organizers,
