Cauchy convergence in V-normed categories
Maria Manuel Clementino, Dirk Hofmann, Walter Tholen
Building on the notion of normed category as suggested by Lawvere, we introduce notions of Cauchy convergence and cocompleteness which differ from proposals in previous works. Key…
Topological lax comma categories
Maria Manuel Clementino, Dirk Hofmann, Rui Prezado
This paper investigates the interplay between properties of a topological space , in particular of its natural order, and properties of the lax comma category $\mathsf{Top} \Dow…
Notions of Cauchy completeness for normed categories
Dirk Hofmann, Walter Tholen
As already mentioned by Lawvere in his 1973 paper, the characterisation of Cauchy completeness of metric spaces in terms of representability of adjoint distributors amounts to the…
Barr-coexactness for metric compact Hausdorff spaces
Marco Abbadini, Dirk Hofmann
Compact metric spaces form an important class of metric spaces, but the category that they define lacks many important properties such as completeness and cocompleteness. In recent…
