    added to Chern-Weil homomorphism the description of the construction of the refined CW homomorphism by differential functions built using the universal connection as described by Hopkins-Singer.

    The letter PP is used in the first paragraph both for the invariant polynomial and for the total space of the principal bundle. I did not change it as I do not know which one to change to stay in accordance with other entries on the topic. Urs ?

    Thanks. I have changed the invariant polynomial notation to “\langle -\rangle”.

    Thanks!

    I have moved the section to before the “refined” version, renamed to “The plain Chern-Weil homomorphism” (okay?) and instead added pointer to the actual reference Kobayashi-Nomizu 63

    diff, v13, current

  1. Thanks Urs. It looks good for me.

    All right.

    I only see now that the threads split, I had been replying, of course, to your message here.

    L Probably it’s the hyphen bug at work, which keeps haunting the nLab.

    Isn’t it that the category of the other thread is ’nLab’ rather than ’Latest Changes’ here?

  2. As mentioned by David, the category of thread is nLab there.

    Yes, David C is correct. Let me know if the two threads should be merged. I am not aware of any present hyphen bug :-).

    I think there is still a problem with some links on the nLab not working, because hyphens that look the same have different character encodings. I stopped reporting that long ago, but if you have the energy, I will drop a message next time I encounter it.

  3. Ah, yes, please do. We have a similar issue registered on the Technical TODO list (nlabmeta). I think people do it unintentionally, but if anyone is deliberately making a choice, I’d suggest to keep it simple and use the usual Ascii hyphen rather a unicode em or en dash :-).

    I think the problem comes not so much from people making choices, but from some non-trivial transformation happening in the process of a) typing a hyphen into the source code, b) it being rendered (and maybe differently in bulk text and headlines?) and this rendered output c) being copy-and pasted into the next source.

    But I’ll check.
