    Unitary representability of free abelian topological groups 
    Uspenskij, Vladimir V. (Universitat Politècnica de València, 2008-10-01)
    [EN] For every Tikhonov space X the free abelian topological group A(X) and the free locally convex vector space L(X) admit a topologically faithful unitary representation. For compact spaces X this is due to Jorge Galindo.

    Asymptotic proximities 
    Protasov, Igor V. (Universitat Politècnica de València, 2008-10-01)
    [EN] A ballean is a set endowed with some family of subsets which are called the balls. The properties of the family of balls are postulated in such a way that the balleans can be considered as a natural asymptotic ...

    A note on a fixed point theorem for ray oriented maps 
    Arockiasamy, A.; Eldred, Anthony (Universitat Politècnica de València, 2008-10-01)
    [EN] In this paper, we will prove a fixed point theorem for a ray-oriented map defined on a nonempty closed bounded convex subset of a Banach space.

    On pseudo-k-spaces 
    Miranda, Anna Maria (Universitat Politècnica de València, 2008-10-01)
    [EN] In this note a new class of topological spaces generalizingk-spaces, the pseudo-k-spaces, is introduced and investigated. Particu-lar attention is given to the study of products of such spaces, in analogyto what is ...

    Spread of balleans 
    Filali, Mahmoud; Protasov, Igor V. (Universitat Politècnica de València, 2008-10-01)
    [EN] A ballean is a set endowed with some family of balls in such a way that a ballean can be considered as an asymptotic counterpart of a uniform topological space. We introduce and study a new cardinal invariant called ...
