    I added a description of the degenerate affine Hecke algebra to the Hecke algebra page as one of the many variants.

    I added the categorical generalization of Schur's lemma to that page.

    I wrote a short stub on the additive envelope of a category, which Mike Shulman has expanded.

    I mentioned the generalization of the Morse lemma to Hilbert manifolds.

    I added the generalization of Hilbert's basis theorem to the case of where the ground ring is noetherian (not necessarily a field).

    I wrote a short page on the Eilenberg swindle.

    So, what is the reference for Morse lemma for Hilbert manifolds ? I might have seen it, but too long time ago to remember...Note the difference in iTeX between writing $Ax$ and $A x$.

    It's in Differential and Riemannian Manifolds by Serge Lang.

    E-synchronicity strikes again!

    I was doing a study and e-lecture ramble on DARM a few years back …

    Lemme track it down and see if I can find a copy of my notes out there …
