Manifolds with Density: Fuller References

SELECTED PUBLICATIONS IN THE HISTORY OF MANIFOLDS WITH DENSITY:

[1959] A. J. Stam, Some inequalities satisfied by the quantities of information of Fisher and Shannon, Indo. Control 2 (1959), 101-112, Eqn. 2.3. Gives a version of Gaussian log-Sobolev inequality, used by Perelman, often attributed to Gross [1975] or sometimes Federbush [1969].

[1966] E. Nelson, A quartic interaction in two dimensions, mathematical Theory of Elementary Particles (Goodman, R. and Segal, I., eds.), MIT Press, 1966, 69-73. Gross [G] says that the entire subject of logarithmic Sobolev inequalities and contractivity properties of semigroups was started in this paper.

[1966] Harper, L. H. Optimal numberings and isoperimetric problems on graphs. J. Combinatorial Theory 1 1966 385-393. Apparently uses measure and metric, cited by Ledoux-Talagrand [1991], both cited by [Ros, §1.4, p. 182].

[1969] Paul Federbush, A partially alternate derivation of a result of Nelson, J. Math. Phys. 10 (1969), 50-52. Gives Gaussian log-Sobolev inequality, used by Perelman, often attributed to Gross [1975], actually probably due to Stam [1959].

[1970] André Lichnerowicz, Variétés riemanniennes a tenseur C non négatif, C. R. Acad. Sci. Paris Sér. A-B 271 (1970), A650-A653. Studies Ric – Hess log density to prove splitting theorems.

[1973] E Nelson, The free Markov field, J. Funct. Analy. 12, 211-227. Gross survey ([G] below) says equivalent form of Gaussian log-Sobolev inequality.

[1975] Gross, Leonard, Logarithmic Sobolev inequalities. Amer. J. Math. 97 (1975), no. 4, 1061-1083.  Proves Gaussian log-Sobolev inequality, used by Perelman. Not yet realized that it was trivial consequence of Gaussian isoperimetric inequality via analytic version which [Ros,  §3.4] traces back to Ehrhard [E, 1984] and Bobkov [B7, 1997], first observed by Ledoux ’94 and Beckner ’96 (published [1999]) (see Morgan Blog and email from Milman). Precursors are Stam [1959] and Federbush [1969] (see Gross survey [G]).

“The notion of a weighted Laplacian was introduced by I. Chavel and E. Feldman [1991] and by E. B. Davies [D, 1992]. Many facts from the analysis on weighted manifolds are similar to those on Riemannian manifolds. However, in the former setting one has an added flexibility of changing the measure without changing the underlying Riemannian structure, which happens to be a powerful technical tool, as was earlier observed by E. B. Davies and B. Simon [1984]. A natural setup for this approach would be a metric measure space with an energy form in the spirit of [FOT, 1994], but this would bring additional technical complications, caused by the singularity of the space.” Ex. 2.1. Scaling metric by a(x) and measure by b(x) yields new Laplacian (1/b)div((b/a)grad). 2.4. Laplacian on model manifolds (surfaces with density of revolution). Lapµ = ∂2/∂r2 + m(r) ∂/∂r + ψ-2 Lap_theta m(r) = (log S(r))’ = (n-1)(log g(r))’ + 2ψ’.

A 0-1 law lemma cited by MR of Borell’s [1975] proof of Gaussian isop. inequality: in Gauss space G^n, if convex C about origin has same volume as halfspace containing origin, then for a > 1, |aC| >= |aH|. Relatively trivial proof just uses Brunn-Minkowski for S^n-1. Result also easily from Gaussian isop. inequality because halfspace minimizes not only perimeter but also x dot unit normal at closest boundary approach to origin and then goes farther in lower density and turns less than C.
