    Add uniform differentiability. (This could also be split into its own page, like continuous differentiability was, if people want to write more about it.)

  1. uniform differentiability and ptwise differentiability with UC derivative ARE EQUIVALENT (under dependent choice)

    for an early reference, I have added pointer to

    • Lev Pontrjagin, Chapter I of: Smooth manifolds and their applications in Homotopy theory, Trudy Mat. Inst. im Steklov, No 45, Izdat. Akad. Nauk. USSR, Moscow, 1955 (AMS Translation Series 2, Vol. 11, 1959) (doi:10.1142/9789812772107_0001, pdf)

    Maybe I should give this its own category:reference-entry…
