A note on completeness of weighted normed spaces of analytic functions
[EN] Given a non-negative weight v, not necessarily bounded or strictly positive, defined on a domain G in the complex plane, we consider the weighted space H-v(infinity) (G)of all holomorphic functions on G such that the product v vertical bar f vertical bar is bounded in G and study the question of when such a space is complete under the canonical sup-seminorm. We obtain both some necessary and some sufficient conditions in terms of the weight v, exhibit several relevant examples, and characterize completeness in the case of spaces with radial weights on balanced domains.The first author was partially supported by MTM2013-43540-P and MTM2016-76647-P by MINECO/FEDER-EU and GVA Prometeo II/2013/013.

Operator theory and function theory in Drury-Arveson space and its quotients
The Drury-Arveson space , also known as symmetric Fock space or the
-shift space, is a Hilbert function space that has a natural -tuple of
operators acting on it, which gives it the structure of a Hilbert module. This
survey aims to introduce the Drury-Arveson space, to give a panoramic view of
the main operator theoretic and function theoretic aspects of this space, and
to describe the universal role that it plays in multivariable operator theory
and in Pick interpolation theory.Comment: Final version (to appear in Handbook of Operator Theory); 42 page
A characterization of the two-weight inequality for Riesz potentials on cones of radially decreasing functions
From Grushin to Heisenberg via an isoperimetric problem
Geodesic in the Heisenberg groups are shown to arise from a isoperimetric problem in the Grushin plan
Paley–Wiener Theorems on the Siegel Upper Half-Space
In this paper we study spaces of holomorphic functions on the Siegel upper half-space
U and prove Paley\u2013Wiener type theorems for such spaces. The boundary of U can
be identified with the Heisenberg group Hn. Using the group Fourier transform on
Hn, Ogden and Vagi (Adv Math 33(1):31\u201392, 1979) proved a Paley\u2013Wiener theorem
for the Hardy space H2(U). We consider a scale of Hilbert spaces on U that includes
the Hardy space, the weighted Bergman spaces, the weighted Dirichlet spaces, and
in particular the Drury\u2013Arveson space, and the Dirichlet space D. For each of these
spaces, we prove a Paley\u2013Wiener theorem, some structure theorems, and provide
some applications. In particular we prove that the norm of the Dirichlet space modulo
constants D\u2d9 is the unique Hilbert space norm that is invariant under the action of the
group of automorphisms of
