Reminiscences on science at I.H.E.S. A problem on homoclinic theory and a brief review
On the occasion of the 40-th anniversary of IHES I present a few scientific
reminiscences: most of my scientific life has been marked by my visits and I
run through them concluding with the analysis of a problem that originated
during my last visit. The problem is to develop a convergent perturbative
algorithm for the construction of the ``Eliasson's potential'' for the stable
and unstable manifolds of an invariant torus: and to study its properties. A
brief review follows.Comment: 70 Kb; 15 pages, plain TeX, 3 figure
Iron Rings, Doctor Honoris Causa Raoul Bott, Carl Herz, and a Hidden Hand
The degree of Doctor of Sciences, honoris causa, was conferred on Raoul Bott
by McGill University in 1987. Much of the work to make this happen was done by
Carl Herz. Some of the author's personal recollections of both professors are
included, along with some context for the awarding of this degree and ample
historical tangents. Some cultural aspects occurring in the addresses are
elaborated on, primarily, the Canadian engineer's iron ring. This paper also
reprints both the convocation address of Raoul Bott and the presentation of
Carl Herz on that occasion.Comment: An edited and reformatted version of this paper, with an additional
photo, will appear in a volume dedicated to Raoul Bott. The author hopes to
expand on some aspects of this preprint in future version

Vitaly Ginzburg and High Temperature Superconductivity: Personal Reminiscences
I offer some personal reminiscences from the period of 1976-1983, when I was
a M. Sc. and then a Ph.D. student in Vitaly L. Ginzburg's High Temperature
Superconductivity group at the P.N. Lebedev Institute in MoscowComment: To be published in proceedings of the Notre Dame Workshop on the
Possibility of Room Temperature Superconductivity, June 2005 v.2: an apposite

Melnikov's approximation dominance. Some examples
We continue a previous paper to show that Mel'nikov's first order formula for
part of the separatrix splitting of a pendulum under fast quasi periodic
forcing holds, in special examples, as an asymptotic formula in the forcing
rapidity.Comment: 46 Kb; 9 pages, plain Te
Quantum invariants of periodic three-manifolds
Let p be an odd prime and r be relatively prime to p. Let G be a finite
p-group. Suppose an oriented 3-manifold M-tilde has a free G-action with orbit
space M. We consider certain Witten-Reshetikhin-Turaev SU(2) invariants w_r(M).
We will give a fomula for w_r(M) in terms of the defect of M-tilde --> M and
the number of elements in G. We also give a version of this result if M and
M-tilde contain framed links or colored fat graphs. We give similar formulas
for non-free actions which hold for a specified finite set of values for r.Comment: 19 pages. Published copy, also available at
