    More Flipping Strange Goings On

    In the past few MGF seminars, we've seen examples of dualities between
    concrete categories which are representable, and where both functors are
    represented by "the same object in different categories".

    In this talk, I hope to discuss some general nonsense which sheds a bit of
    light on the situation, and to present a small selection of examples which
    don't come from the Stone Duality part of the world; perhaps Pontyragin
    duality, Gelfand Duality, or the recovery of smooth manifolds from their
    rings of smooth real-valued functions.
