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, Joaquín 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 se…
Hypercontractivity and strips of convergence in Hardy spaces of general Dirichlet series
Daniel Carando, Andreas Defant, Felipe Marceca +2
For a general Dirichlet series with frequency , we study how horizontal translation (i.e. convolution with a Poisson kernel) improves its integrabi…
Eigenvalue estimates for Fourier concentration operators on two domains
Felipe Marceca, José Luis Romero, Michael Speckbacher
We study concentration operators associated with either the discrete or the continuous Fourier transform, that is, operators that incorporate a spatial cut-off and a subsequent fre…
Improved discrepancy for the planar Coulomb gas at low temperatures
Felipe Marceca, José Luis Romero
We study the planar Coulomb gas in the regime where the inverse temperature grows at least logarithmically with respect to the number of particles (freezing regime, $β_n\…
Gaussian beta ensembles: the perfect freezing transition and its characterization in terms of Beurling-Landau densities
Yacin Ameur, Felipe Marceca, José Luis Romero
The Gaussian -ensemble is a real -point configuration picked randomly with respect to the Boltzmann factor , $H_n=\sum_{i\ne j}\log\frac 1{|x_i…
Spectral deviation of concentration operators for the short-time Fourier transform
Felipe Marceca, José Luis Romero
Time-frequency concentration operators restrict the integral analysis-synthesis formula for the short-time Fourier transform to a given compact domain. We estimate how much the cor…
Decoupling inequalities with exponential constants
Daniel Carando, Felipe Marceca, Pablo Sevilla-Peris
Decoupling inequalities disentangle complex dependence structures of random objects so that they can be analyzed by means of standard tools from the theory of independent random va…
Vector-valued general Dirichlet series
D. Carando, A. Defant, F. Marceca +1
Opened up by early contributions due to, among others, H. Bohr, Hardy-Riesz, Bohnenblust-Hille, Neder and Landau the last 20 years show a substantial revival of systematic research…
Hausdorff-Young type inequalities for vector-valued Dirichlet series
Daniel Carando, Felipe Marceca, Pablo Sevilla-Peris
We study Hausdorff-Young type inequalities for vector-valued Dirichlet series which allow to compare the norm of a Dirichlet series in the Hardy space with th…
Random unconditional convergence of vector-valued Dirichlet series
Daniel Carando, Felipe Marceca, Melisa Scotti +1
We study random unconditionality of Dirichlet series in vector-valued Hardy spaces . It is shown that a Banach space has type 2 (respectively, cotype 2) if and…
Some remarks on non-symmetric polarization
Felipe Marceca
Let be an -homogeneous polynomial given by \[P(x)= \sum_{1\leq j_1\leq \ldots \leq j_m \leq n} c_{j_1 \ldots j_m} x_{j_1}\ldots x_{j_m}.\]…
