Spectral deviation of concentration operators on reproducing kernel Hilbert spaces
Felipe Marceca, José Luis Romero, Michael Speckbacher +1
We study the eigenvalue profile of concentration operators (multiplication by an indicator function followed by projection) acting on reproducing kernel Hilbert spaces. The spectra…

Sampling properties of the zeroes of the Gaussian entire function
Jeremiah Buckley, Felipe Marceca, JoaquÃn Singer
We study sampling properties of the zero set of the Gaussian entire function on Fock spaces. Firstly, we relax Seip and Wallstén's density and separation conditions for sampling s…
