On the correlation between nodal and boundary lengths for random spherical harmonics

Abstract

We study the correlation between the nodal length of random spherical harmonics and the measure of the boundary for excursion sets at any non-zero level. We show that the correlation is asymptotically zero, while the partial correlation after controlling for the random L2L^2-norm on the sphere of the eigenfunctions is asymptotically one.
