    A Note on the Spectrum of Some Composition Operators on Korenblum Type Spaces 
    Galindo, Pablo; Gomez-Orts, Esther (Springer-Verlag, 2021-05)
    [EN] We prove that under some mild conditions on the symbol phi, the spectrum of the corresponding composition operator C-phi on the Korenblum type spaces A_(-alpha) and A(+)(-alpha) contains a closed ball of positive radius.

    Homomorphisms between algebras of holomorphic functions 
    Dimant, Verónica; García, Domingo; Maestre, Manuel; Sevilla Peris, Pablo (Hindawi Publishing Corporation, 2014)
    For two complex Banach spaces X and Y, in this paper, we study the generalized spectrum M-b(X,Y) of all nonzero algebra homomorphisms from H-b(X), the algebra of all bounded type entire functions on X into H-b(Y). We endow ...

    On the spectra of algebras of analytic functions 
    Carando, Daniel G.; García Rodríguez, Domingo; Maestre Vera, Manuel; Sevilla Peris, Pablo (American Mathematical Society, 2012)
    In this paper we survey the most relevant recent developments on the research of the spectra of algebras of analytic functions. We concentrate mainly in three algebras, the Banach algebra H∞(B) of all bounded holomorphic ...

    The spectrum of Volterra operators on Korenblum type spaces of analytic functions 
    Bonet Solves, José Antonio (Springer-Verlag, 2019-10)
    [EN] The continuity, compactness and the spectrum of the Volterra integral operator V-g with symbol an analytic function g, when acting on the classical Korenblum space and other related weighted Frechet or (LB) spaces of ...

    Weighted composition operators on Korenblum type spaces of analytic functions 
    Gomez-Orts, Esther (Springer-Verlag, 2020-09-05)
    [EN] We investigate the continuity, compactness and invertibility of weighted composition operators W-psi,W-phi: f -> psi(f circle phi) when they act on the classical Korenblum space A(-infinity) and other related Frechet ...
