    Convolution operators supporting hypercyclic algebras 
    Bès, Juan P.; Conejero, J. Alberto; Papathanasiou, Dimitris (Elsevier, 2017)
    [EN] We show that any convolution operator induced by a non-constant polynomial that vanishes at zero supports a hypercyclic algebra. This partially solves a question raised by R. Aron

    Smooth functions with uncountably many zeros 
    Conejero, J. Alberto; Muñoz-Fernández, Gustavo A.; Murillo Arcila, Marina; Seoane Sepúlveda, Juan Benigno (Belgian Mathematical Society, 2015)
    [EN] In this short note we show that there exist uncountably generated alge- bras every non-zero element of which is a smooth function having uncount- ably many zeros. This result complements some recent ones by Enflo et ...

    When the Identity Theorem "seems" to fail 
    Conejero Casares, José Alberto; Jiménez Rodríguez, Pablo; Muñoz-Fernández, Gustavo A.; Seoane-Sepúlveda, Juan B. (Mathematical Association of America (MAA), 2014-01)
    The Identity Theorem states that an analytic function (real or complex) on a connected domain is uniquely determined by its values on a sequence of distinct points that converge to a point of its domain. This result is ...
