Sign-balance of random Laplace eigenfunctions

Stephen Muirhead, Igor Wigman

Motivated by the problem of the small-scale sign distribution of Laplace eigenfunctions, we introduce a strong notion of sign-balance for (eigen)functions, and prove that random ei…

On the supremum of random cusp forms

Bingrong Huang, Stephen Lester, Igor Wigman +1

A random ensemble of cusp forms for the full modular group is introduced. For a weight- cusp form, restricted to a compact subdomain of the modular surface, the true order of ma…

The giant component of excursion sets of spherical Gaussian ensembles: existence, uniqueness, and volume concentration

Stephen Muirhead, Igor Wigman

We establish the existence and uniqueness of a well-concentrated giant component in the supercritical excursion sets of three important ensembles of spherical Gaussian random field…

Eigenvalue clusters for the hemisphere Laplacian with variable Robin condition

Alexander Pushnitski, Igor Wigman

We study the eigenvalue clusters of the Robin Laplacian on the 2-dimensional hemisphere with a variable Robin coefficient on the equator. The 'th cluster has eigenva…

Around the Gauss circle problem: Hardy's conjecture and the distribution of lattice points near circles

Stephen Lester, Igor Wigman

Hardy conjectured that the error term arising from approximating the number of lattice points lying in a radius- disc by its area is . One source of support for…

Almost sure GOE fluctuations of energy levels for hyperbolic surfaces of high genus

Zeév Rudnick, Igor Wigman

We study the variance of a linear statistic of the Laplace eigenvalues on a hyperbolic surface, when the surface varies over the moduli space of all surfaces of fixed genus, sample…
