    a stub entry, for the moment just to unbreak an early link offered at separation axioms in terms of lifting properties

    I moved some of Misha Gavrilovich’s material from lift to here, and re-formatted/re-typeset somewhat.

    (Should try to remember how to typeset pre-superscripts in Instiki…)

    Made weak orthogonal class etc. redirect here.

    Also cross-linked with injective or projective morpshism. These two entries might deserve to be merged, but I won’t do it right now.

    After numerous failed attempts, I figured out how to typeset

    (M ⧄) ⧄\multiscripts{^⧄}{\big(M^{⧄}\big)}{}

    namely

      \multiscripts{^⧄}{\big(M^{⧄}\big)}{}
