Excursion Fluctuations and Spectral Universality in Gaussian Fields

Dmitry Beliaev, Akshay Hegde

We study the large-scale spatial fluctuations of excursion volumes for a class of smooth stationary Gaussian fields. In the case of Berry's random wave model in dimension $d \geq 2…

High local maxima of stationary smooth Gaussian fields

Dmitry Beliaev, Akshay Hegde

Consider the point process (in ) of local maxima of smooth Gaussian fields, with sufficient decay of correlation at infinity, above a level . We show that this poi…

A covariance formula for topological events of smooth Gaussian fields

Dmitry Beliaev, Stephen Muirhead, Alejandro Rivera

We derive a covariance formula for the class of `topological events' of smooth Gaussian fields on manifolds; these are events that depend only on the topology of the level sets of…

A covariance formula for the number of excursion set components of Gaussian fields and applications

Dmitry Beliaev, Michael McAuley, Stephen Muirhead

We derive a covariance formula for the number of excursion or level set components of a smooth stationary Gaussian field on contained in compact domains. We also pre…

A central limit theorem for the number of excursion set components of Gaussian fields

Dmitry Beliaev, Michael McAuley, Stephen Muirhead

For a smooth stationary Gaussian field on and level , we consider the number of connected components of the excursion set (or l…
