    (the complex numbers appeared as “𝔹\mathbb{B}” a few lines in a row, apparently copy-and-pasted onwards)

    fixed another typo

    (in a formula inside a proof, a universal bundle EU(n)E U(n) should have been its base space BU(n) B U(n)).

    It makes no sense that this Lemma – on the Thom space of the universal line bundle being weakly homotopy equivalent to the base space – is hidden within this entry here.

    Therefore I will (later today) give this lemma its own stand-alone page:

    This will also make room to spell out a less sketchy proof of it.
