  • Optimization of Financial Indicators in Shale-Gas Wells Combining Numerical Decline Curve Analysis and Economic Data Analysis 

    Soage Quintáns, Manuel Andrés; Juanes, Rubén; Colominas, Ignasi; Cueto-Felgueroso Landeira, Luis (MDPI, 2024)
    [Abstract:] We present a methodology to determine optimal financial parameters in shale-gas production, combining numerical simulation of decline curves and stochastic modeling of the gas price. The mathematical model of ...
  • On local cross sections in topological abelian groups 

    Bello, Hugo J.; Chasco, MJ; Domínguez, Xabier; Stevens, T. Christine (Springer, 2018)
    [Abstract:] We introduce the notion of local pseudo-homomorphism between two topological abelian groups. We prove that it is closely related with the widely studied notions of local cross sections and splitting extensions ...
  • On g-barrelled groups and their permanence properties 

    Borsich, Tayomara; Chasco, MJ; Domínguez, Xabier; Martín Peinador, Elena (Elsevier, 2019)
    [Abstract:] The g-barrelled groups constitute a vast class of abelian topological groups. It might be considered as a natural extension of the class of barrelled topological vector spaces. In this paper we prove that ...
  • On the existence of topologies compatible with a group duality with predetermined properties 

    Borsich, Tayomara; Domínguez, Xabier; Martín Peinador, Elena (Elsevier, 2022)
    [Abstract:] The paper deals with group dualities. A group duality is simply a pair (G, H) where G is an abstract abelian group and H a subgroup of characters defined on G. A group topology τ defined on G is compatible with ...
  • Permutations, Signs, and Sum Ranges 

    Chobanyan, Sergei; Domínguez, Xabier; Tarieladze, Vaja; Vidal, Ricardo (MDPI, 2023)
    [Abstract:] The sum range SR[x; X], for a sequence x = (xn)n∈N of elements of a topological vector space X, is defined as the set of all elements s ∈ X for which there exists a bijection (=permutation) π : N → N, such that ...
