This generalizes results spread in the literature including the general (proximal) hit-and-miss topologies, as well as various topologies generated by gap and excess functionals. It is also shown that the Vietoris hyperspace can be non-Baire even if the base space is a 2nd countable Hausdorff Baire space.Reconocimiento - No comercial - Sin obra derivada (by-nc-nd)Baire spacesApproach spaces(Proximal) hit-and-miss topologiesWeak hypertopologiesBanach-Mazur gameBaire spaces and hyperspace topologies revisitedArtÃculo2014-10-2310.4995/agt.2014.1897Abierto1989-4147
