Stability of global wave front sets by perturbations of frames

Chiara Boiti, David Jornet, Alessandro Oliaro

In this paper we consider the Gabor wave front set of ultradistributions in the frame of ultradifferentiable functions. We prove that such a wave front set, defined through a Gabor…

On the compactness of the Weyl operator in

Vicente Asensio, Chiara Boiti, David Jornet +1

We characterize, using time-frequency analysis, the continuity and compactness of the Weyl operator in global classes of ultradifferentiable functions , for weight f…

On the inclusion relations of global ultradifferentiable classes defined by weight matrices

Chiara Boiti, David Jornet, Alessandro Oliaro +1

We study and characterize the inclusion relations of global classes in the general weight matrix framework in terms of growth relations for the defining weight matrices. We conside…

Construction of the log-convex minorant of a sequence

Chiara Boiti, David Jornet, Alessandro Oliaro +1

We give a simple construction of the log-convex minorant of a sequence and consequently extend to the -dimensional case the well-known formula tha…

Mean ergodic composition operators on spaces of holomorphic functions on a Banach space

David Jornet, Daniel Santacreu, Pablo Sevilla-Peris

We study mean ergodic composition operators on infinite dimensional spaces of holomorphic functions of different types when defined on the unit ball of a Banach or a Hilbert space:…

Nuclear global spaces of ultradifferentiable functions in the matrix weighted setting

Chiara Boiti, David Jornet, Alessandro Oliaro +1

We prove that the Hermite functions are an absolute Schauder basis for many global weighted spaces of ultradifferentiable functions in the matrix weighted setting and we determine…

Mean ergodic composition operators in spaces of homogeneous polynomials

David Jornet, Daniel Santacreu, Pablo Sevilla-Peris

We study some dynamical properties of composition operators defined on the space of -homogeneous polynomials on a Banach space when i…

Nuclearity of rapidly decreasing ultradifferentiable functions and time-frequency analysis

Chiara Boiti, David Jornet, Alessandro Oliaro +1

We use techniques from time-frequency analysis to show that the space of rapidly decreasing -ultradifferentiable functions is nuclear for every weight function $ω…
