These articles should be ported to the [[nLab:HomePage|nLab]] or merged into the existing article on the [[nLab:HomePage|nLab]] because although the concepts in many of the articles were originally developed in homotopy type theory, they are general enough that they should be of interest to constructive mathematicians who do not use homotopy type theory as foundations. * [[premetric space]] * [[Cauchy net]] * [[modulus of Cauchy convergence]] * [[Cauchy approximation]] * [[Cauchy structure]] * [[HoTT book real numbers]] * [[Cauchy real numbers]] * [[generalized Cauchy real numbers]] * [[Cauchy real numbers (disambiguation)]]
