Re: Kinetic Energy Is A Riemann Metric On Configuration Space (fwd)

[Johannes Huebschmann]

Dear All

Last thursday I had sent a message to Harry Dole
but wasn't sure whether it might interest others and
did not send it to the list.
Since the discussion continues, here is a copy of my
message to Harry Dole.

Dear Harry

This is great.
Many thanks indeed.

In 1977 (or so) Mac Lane gave a talk at Heidelberg
and mentioned
Max and Min, Lax and Lin,
the principle of Courant-Weyl
and other such issues.
From my recollections
he did not say he had ever taught a course on mechanics.

If I had obtained a copy of these notes in my mathematical youth,
that would have saved me a lot of trouble.

Best wishes

Johannes

Dear Johannes et al,

Well, let's give some thought to Rob Goldblatt.  I met Rob in New Zealand
at a sumptuous September dinner.

I've been out of touch with the categorical community for a while so
meeting Rob was a treat.  I disclosed to him I had Saunders' old notes, and
he advised they could be of interest to this list.  I had no idea.
Apologies for not posting sooner.

cheers,

harry
