چکیده

We show that every real analytic action of a connected supersoluble Lie group on a compact surface with nonzero Euler characteristic has a fixed point. This implies that E. Lima’s fixed point free C∞ action on S of the affine group of the line cannot be approximated by analytic actions. An example is given of an analytic, fixed point free action on S of a solvable group that is not supersoluble.

Rigidity of Trivial Actions of Abelian-by-cyclic Groups

The question of existence and stability of global fixed points for group actions has been studied in many different contexts. In the setting of actions of Lie groups it was shown by Lima [8] that n commuting vector fields on a genus g surface, Σg, of non-zero Euler characteristic have a common singularity. This implies that any action of the abelian Lie group R on Σg has a global fixed point. I...

2 2 D ec 1 99 9 Linearization Problems for Lie Algebroids and Lie Groupoids In memory of Moshé Flato , 1938 - 1999

Why is it so hard to prove the linearizability of Poisson structures with semisimple linear part? Conn published proofs about 15 years ago in a pair of papers [5][6] full of elaborate estimates. Except for the somewhat more conceptual reformulation by Desolneux-Moulis [9] in the smooth case, no simplification of Conn’s proofs has appeared. This is a mystery to me, because analogous theorems abo...

Local rigidity of certain partially hyperbolic actions of product type

We prove certain rigidity properties of higher-rank abelian product actions of the type α × Id N : Z κ → Diff(M × N), where α is (TNS) (i.e. is hyperbolic and has some special structure of its stable distributions). Together with a result about product actions of property (T) groups, this implies the local rigidity of higher-rank lattice actions of the form α × Id T : → Diff(M × T), provided α ...

Fixed Points of Local Actions of Lie Groups on Real and Complex 2-Manifolds

I discuss old and new results on fixed points of local actions by Lie groups G on real and complex 2-manifolds, and zero sets of Lie algebras of vector fields. Results of E. Lima, J. Plante and C. Bonatti are reviewed.
