A note on a Halmos problem
Maximiliano Contino, Eva Gallardo-Gutierrez
We address the existence of non-trivial closed invariant subspaces of operators on Banach spaces whenever their square have or, more generally, whether there exists a pol…
Invariant subspaces of the Cesaro operator
Eva A. Gallardo-Gutierrez, Jonathan R. Partington, William T. Ross
This paper explores various classes of invariant subspaces of the classical Cesàro operator on the Hardy space . We provide a new characterization of the finite co-dimensi…
Zero-free regions of the Riemann zeta function and approximation in weighted Dirichlet spaces
Eva Gallardo-Gutiérrez, Daniel Seco
We study zero-free regions of the Riemann zeta function related to an approximation problem in the weighted Dirichlet space which is known to be equivalent to the Riem…
On generators of -semigroups of composition operators
Eva A. Gallardo-Gutiérrez, Dmitry Yakubovich
Avicou, Chalendar and Partington proved that an (unbounded) operator on the classical Hardy space generates a semigroup of composition operators if and only…
Weighted composition operators on the Dirichlet space: boundedness and spectral properties
I. Chalendar, E. A. Gallardo-Gutiérrez, J. R. Partington
Boundedness of weighted composition operators acting on the classical Dirichlet space as is studied in terms of the multiplier sp…
