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. ## Articles needed to be ported to the nlab ## * [[sequence]] * [[sequential derivative]] * [[sequential antiderivative]] * [[left shift operator]] * [[right shift operator]] * [[series operator]] * [[inverse series operator]] ## Articles ported to the nLab ## * [[decimal numbers]] * [[rational numbers]] * [[irrational numbers]] * [[real numbers]] * [[sequentially Hausdorff space]] * [[quotient set]] * [[setoid]] * [[groupoid]] * [[closed interval]] * [[lower bounded open interval]] * [[upper bounded open interval]] * [[open interval]] * [[unit interval]]
