Bianca Dittrich saves the loopski bacon?

  • Thread starter marcus
  • Start date
In summary, the conversation discusses a paper by Dittrich which introduces a new method for generating more observables in canonical GR, leading to the possibility of more progress in the Loop program with less complexity. The participants also express excitement and admiration for Dittrich's work and discuss the potential implications for the physics department, with one participant joking about becoming a Dean.

Just as I was going to simplify my life by going all out Triangles
along comes this paper where
she's got a line on the loopski hamiltonian.

http://arxiv.org/gr-qc/0507106

or suspiciously like that.

selfAdjoint or somebody. tell me what's wrong
or that I'm dreaming. It looks to me like the kind of
things that were SUPPOSED to happen in the Loop program
are little by little happening. And maybe going a bit lighter
on the machinery than with the earlier masterconstraint
methodology. more the eagle feather and less of the cudgel.
or am I mistaken?

Yes Marcus, I've been studying this Dittrich paper, and it seems to be very exciting. As she says, decades of work by GR theorists, string theorists, and quantum gravity theorists have only come up with ten complete observables, plus one extra that some bright researcher found, whereas there must be beaucoup of them because canonical GR has a continuum of first class constraints. "For each point [tex]\sigma \in \Sigma [/tex]there are d diffeomorphism constraints..." (sentence leading to equation (35), which displays the form of the constraints. Now she has a method for generating many, many more.

Let's send her flowers :wink:

With thinking like that you'll be a Dean someday.

Sounds great! I'll appoint Renate Loll to chair the physics department!
How many secretaries do Deans get?
