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 classical and constructive mathematicians who do not use homotopy type theory as foundations. * [[inverse image]] * [[iterated inverse image]] * [[infinitely iterated inverse image]] * [[an axiomatization of the real numbers]] category: not redirected to nlab yet
