When is this braiding not a symmetry?
@ Fernando - I also see that I had calculated the obstruction to the braiding being a symmetry in terms of the monoid multiplication, an obstruction which, as you point out, is not zero in general. |

When is this braiding not a symmetry?
@Fernando, thanks, I see that now - the Moore loops and the ordinary loop space are of the same homotopy type. |

Isn't it true that when X is itself a topological monoid (and not just a loop space) the quadratic map eta* is in fact a homomorphism? In any case I think one can use the monoid product to show that the braiding is its own homotopy inverse whenever X is a topological monoid. |

Notes for Bott's 1963 lectures on Morse theory
Sorry for my careless reading of your request. The K(x) lectures date from 1963 also. |

P.S. Just noticed that this is a scan of an autographed copy. Can't do better than that! |

These notes were published by Benjamin in 1969 under the title "Lectures on K(X). Here is a link to a scanned copy: google.com/… |

What are the algebras for the double dualization monad?
For more information on linearly compact vector spaces from a categorical point of view see section 24 of the Bergman and Hausknecht book "Cogroups and Co-rings in Categories of Associative Rings". |
