| May 5, 2010 at 20:19 | comment | added | Benoît Kloeckner | Regarding your last question, it reminds me of Zimmer programm, according to which any volume-preserving action of a lattice in a Lie group of rank n (e.g. SL(n+1;R)) on a manifold of dimension <n should be trivial in the sense that it factors through a finite group | |

| May 5, 2010 at 14:12 | comment | added | algori | macbeth -- thanks. Re the Mobius part of the question: I've taken a brief look at the paper by Goldman and it seems the answer is yes since according to the paper the representation corresponding to the developing map is by conformal diffeomorphisms. | |

| May 5, 2010 at 13:35 | comment | added | macbeth | Rephrasings are useful, so I'll ask about one that occurs to me. Is it true that in dim>2 a "Möbius" (respectively, "projective") manifold is the same as a conformally flat (respectively, projectively flat) manifold? That is, a manifold equipped with a conformal equivalence class of metrics (respectively, a projective equivalence class of connections), including for each point a representative which is flat in a n/hd of that point. If so, here's an '83 paper producing a few counterexamples in the Möbius 3-case. | |
