    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.

    A Survey on Nikodým and Vitali-Hahn-Saks Properties 
    López Alfonso, Salvador; López-Pellicer, Manuel; Mas Marí, José (Y&#305lmaz Simsek, 2021)
    [EN] Let ba(A) be the Banach space of the real (or complex) finitely additive measures of bounded variation defined on an algebra A of subsets of Omega and endowed with the variation norm. . A subset B of A is a Nikod ́ym ...

    A Survey on Valdivia Open Question on Nikodým Sets 
    López Alfonso, Salvador; López Pellicer, Manuel; Moll López, Santiago Emmanuel; Sánchez Ruiz, Luis Manuel (MDPI AG, 2022-08)
    [EN] Let A be an algebra of subsets of a set W and ba(A) the Banach space of bounded finitely additive scalar-valued measures on A endowed with the variation norm. A subset B of A is a Nikodým set for ba(A) if each countable ...

    Baire-Type Properties in Metrizable c(0)(omega, X) 
    López Alfonso, Salvador; López Pellicer, Manuel; Moll López, Santiago Emmanuel (MDPI AG, 2022-01)
    [EN] Ferrando and Lüdkovsky proved that for a non-empty set $\Omega $\ and a normed space $X$, the normed space $c_{0}(\Omega ,X)$ is barrelled, ultrabornological, or unordered Baire-like if and only if $X$ is, respectively, ...

    Classifying Topologies through G-Bases 
    Ferrando, Juan Carlos; López Pellicer, Manuel (MDPI AG, 2022-12-19)
    [EN] We classify several topological properties of a Tychonoff space $X$ by means of certain locally convex topologies $\mathcal{T}$ with a $\mathfrak{G}$-base located between the pointwise topology $\tau _{p}$ and the ...

    Distinguished Property in Tensor Products and Weak* Dual Spaces 
    López Alfonso, Salvador; López Pellicer, Manuel; Moll López, Santiago Emmanuel (MDPI AG, 2021-09)
    [EN] A local convex space $E$ is said to be distinguished if its strong dual $E_{\beta }^{\prime }$ has the topology $\beta (E^{\prime },(E_{\beta}^{\prime })^{\prime })$, i.e., if $E_{\beta }^{\prime }$ is barrelled. ...

    On Four Classical Measure Theorems 
    López Alfonso, Salvador; López Pellicer, Manuel; Moll López, Santiago Emmanuel (MDPI AG, 2021-03)
    [EN] A subset B of an algebra A of subsets of a set Omega has property (N) if each B-pointwise bounded sequence of the Banach space ba(A) is bounded in ba(A), where ba(A) is the Banach space of real or complex bounded ...

    On weakly compact sets in C(X) 
    Ferrando, J. C.; López Alfonso, Salvador (Springer-Verlag, 2021-01-04)
    [EN] A subset A of a locally convex space E is called (relatively) sequentially complete if every Cauchy sequence {x(n)}(n=1)(infinity) in E contained in A converges to a point x is an element of A (a point x is an element ...

    Weak Sequential Convergence in Bounded Finitely Additive Measures 
    López Alfonso, Salvador; López Pellicer, Manuel (Springer, 2020-03)
    [EN] It is well known that a ¿-algebra ¿ of subsets of a set ¿ verifies both Nikodým property and property (G) for the Banach space ba(¿) of bounded finitely additive measures defined in ¿. A classic result of Valdivia ...
