  1. I changed a typo in the definition of the center of a Lie algebra, which was

    “…all elements z∈L z\in L such that [l,z]=0[l,z]=0 for all z∈Lz\in L”.

    Now it is

    “…all elements z∈L z\in L such that [l,z]=0[l,z]=0 for all l∈Ll\in L”.

    I have touched wording and sub-section outline of the section “Center of (higher) categories” (here) in an attempt to make it be less odd.

    Will give center of a category its own little entry, for the moment just so that its easier to link terms properly.
