    Chaos for dynamics of birth-and-death models 
    Aroza Benlloch, Javier (Universitat Politècnica de València, 2011-09-28)
    n this work we will study the chaotic behaviour of infinite dimensional linear systems on Banach spaces, specially we will study the solutionstrongly continuous semigroups of operators of these systems. We will focus on ...

    Convergence semigroup actions: generalized quotients 
    Boustique, H.; Mikusinski, Piotr; Richardson, Gary (Universitat Politècnica de València, 2009-10-01)
    [EN] Continuous actions of a convergence semigroup are investigated in the category of convergence spaces. Invariance properties of actions as well as properties of a generalized quotient space are presented

    Hypercyclic abelian semigroup of matrices on Cn and Rn and k-transitivity (k ≥ 2) 
    Ayadi, Adlene (Universitat Politècnica de València, 2011-04-01)
    [EN] We prove that the minimal number of matrices on Cn required to forma hypercyclic abelian semigroup on Cn is n+1. We also prove that theaction of any abelian semigroup finitely generated by matrices on Cnor Rn is never ...

    Semigroups and their topologies arising from Green's left quasiorder 
    Richmond, Bettina (Universitat Politècnica de València, 2008-10-01)
    [EN] Given a semigroup (S, ·), Green’s left quasiorder on S is given by a ≤ b if a = u · b for some u ϵ S1. We determine which topological spaces with five or fewer elements arise as the specialization topology from Green’s ...
