    a stub, for the moment just to make links work. Wanted to start an Idea section, but need to go offline urgently now. More later.

    added more references. Realized this needs to be merged with references already present at Berry’s phase.

    But I still have trouble editing from within the NYU-AD network, it seems to block the nForum completely now (wasn’t the case before, this here sent via data on my phone) all the editing via ncatlab.org and some of the editing via nlab.preschema.org. I think I may need to contact IT here for help before I can continue editing today.
