Dear all,
next Thursday, May 5th, Riccardo Maffucci (EPFL) will give a seminar about
"Distribution of nodal intersections for random waves".
Abstract: This work is in collaboration with Maurizia Rossi. Random waves are Gaussian Laplacian eigenfunctions on the 3D torus. We investigate the length of intersection between the zero (nodal) set, and a fixed surface. Expectation, and variance in a general scenario are prior work. In the generic setting we prove a CLT. We will discuss (smaller order) variance and (non-Gaussian) limiting distribution in the case of ’static’ surfaces (e.g. sphere). Under a certain assumption, there is asymptotic full correlation between intersection length and nodal area.
The seminar will take place in Aula De Blasi, Università Tor Vergata, at 16h00. We encourage in-person partecipation, but should you unable to come here is the link to the event on Teams:
