    Global pseudodifferential operators in spaces of ultradifferentiable functions 
    Asensio López, Vicente (Universitat Politècnica de València, 2021-10-18)
    [ES] En esta tesis estudiamos operadores pseudodiferenciales, que son operadores integrales de la forma f 7→ ∫ Rd (∫ Rd ei(x−y)·ξa(x,y,ξ)f(y)dy)dξ, en las clases globales de funciones ultradiferenciables de tipo Beurling ...

    Global Wave Front Sets in Ultradifferentiable Classes 
    Asensio López, Vicente; Boiti, Chiara; Jornet Casanova, David; Oliaro, Alessandro (Springer-Verlag, 2022-04)
    [EN] We introduce a global wave front set using Weyl quantizations of pseudodifferential operators of infinite order in the ultradifferentiable setting. We see that in many cases it coincides with the Gabor wave front set ...

    The Wigner global wave front set in spaces of tempered ultradistributions 
    Asensio López, Vicente (Springer, 2023-06)
    [EN] In this paper we introduce and study global wave front sets in terms of the t-Wigner transform in global ultradifferentiable classes of Beurling type modulated with weight functions in the sense of Braun, Meise, and ...
