    Characterizing Fréchet-Schwartz spaces via power bounded operators 
    Albanese, Angela A.; Bonet Solves, José Antonio; Ricker, Werner Joseph (Polskiej Akademii Nauk, Instytut Matematyczny (Polish Academy of Sciences, Institute of Mathematics), 2014-09-29)
    [EN] We characterize Köthe echelon spaces (and, more generally, those Fréchet spaces with an unconditional basis) which are Schwartz, in terms of the convergence of the Cesàro means of power bounded operators defined on ...

    Convergence of arithmetic means of operators in Fréchet spaces 
    Albanese, Angela Ama; Bonet Solves, José Antonio; Ricker, Werner J. (Elsevier, 2013-05-01)
    Every Köthe echelon Fréchet space XX that is Montel and not isomorphic to a countable product of copies of the scalar field admits a power bounded continuous linear operator TT such that I−TI−T does not have closed range, ...
