• Characterization of δ-Hurewicz spaces and spaces of δ-continuous functions 

      Zarco García, Ana María; Bayati, Jalal Hatem Hussein (Gulf Journal of Mathematics, 2025)
      This work explores the properties of δ-Hurewicz spaces, providing characterization for union of spaces, subspaces, and products of such spaces, as well as we identify under which conditions δ-continuous functions have as ...
    • Spaces of Θ-faintly and α-faintly continuous functions and composition operators 

      Zarco García, Ana María; Bayati, Jalal Hatem Hussein; Adeeb, Noor Riyadh (Gulf Journal of Mathematics, 2025)
      This work is dedicated to the study of composition operator Cφ where φ is a continuous function. First, we characterize topologies on Cθ(X,Y), the space of θ-faintly continuous, to establish results for the composition ...
