SUMMARY:Non-archimedean Yomdin-Gromov parametrizations and points of bounded height
DESCRIPTION:In the spirit of work by Pila-Wilkie (2006) and by Pila (2009)\, we will present bounds on the number of points of bounded height in the non-archimedean context. An important tool to make the determinant method work is provided by a non-archimedean version of the Yomdin – Gromov parameterizing lemma. We wil explain these results\, obtained in joint work with G. Comte and F. Loeser.

SUMMARY:Galois equations on torsion points and the Tate-Voloch conjecture on p-adic fields
DESCRIPTION:The Tate-Voloch conjecture is a statement about p-adic distance from torsion points to subvarieties in a semi-abelian variety defined over C_p. The use of Galois equations on torsion points by Pink and Rossler to prove the Manin-Mumford conjecture can be adapted to prove that conjecture in the case where both the semi-abelian variety and its subvariety are defined over a finite extension of Q_p.In this talk\, we will present such a proof\, and try to give an insight on how this proof differs from the model-theoretic one given by Scanlon.

SUMMARY:Pregeometries and definable groups
DESCRIPTION:We describe a recent program for analyzing definable sets and groups in certain model theoretic settings. Those settings include:(a) o-minimal structures (M\, P)\, where M is an ordered group and P is a real closed field defined on a bounded interval (joint work with Peterzil)\,(b) tame expansions (M\, P) of a real closed field M by a predicate P\, such as expansions with o-minimal open core (work in progress with Gunaydin and Hieronymi).The analysis of definable groups first goes through a local level\, where a pertinent notion of a pregeometry and generic elements is each time introduced.

SUMMARY:Valued differential fields
DESCRIPTION:We consider valued fields of equicharacteristic zero equipped with a continuous derivation. This class of structures is rather diverse\, including both monotone differential fields and asymptotic differential fields. (These terms will be defined.) Nevertheless\, some results can be established uniformly for the entire class: algebraic extensions\, construction of residue field extensions\, the Equalizer Theorem\, construction of immediate extensions\, differential-henselianity. Next I will revisit Scanlon’s thesis on the model theory of differential-henselian monotone differential fields with enough constants. Time permitting I will add some remarks on the case of asymptotic differential fields.The above is (a small part of) ongoing joint work with Matthias Aschenbrenner and Joris van der Hoeven focused on developing a model theory for differential fields of transseries.

SUMMARY:Tame definable topological dynamics
DESCRIPTION:(Joint work with Pierre Simon) I will present some new results on definably amenable groups in NIP theories (typical examples of which are definably amenable groups in o-minimal theories\, algebraically closed valued fields and p-adics). In particular I will demonstrate that in this context various notions of genericity coincide (answering some questions of Newelski and Petrykowski) and a characterization of ergodic measures will be given. Arguments rely on the theory of forking for types and measures in NIP theories and the so-called (p\,q)-theorem from combinatorics.If time permits\, I will describe how these results generalize to homogeneous spaces\, ind-definable groups and action of the group of automorphisms\, and how these developments can be viewed as a study of the definable case of abstract tame dynamical systems introduced by Glasner.

SUMMARY:Church-Turing computability of the étale cohomology mod l
DESCRIPTION:[Work in common with Fabrice Orgogozo]The dimension of the étale cohomology groups\, with coefficients in Z/lZ\, of a scheme of finite type over an algebraically closed field of characteristic different from l\, is computable in the sense of Church-Turing. To prove this\, we construct a hypercovering of X by schemes (analogous to Artin’s ?Roegood neighborhoods?R) having algorithmically testable geometric properties which allow to reduce the computation of the cohomology of X to that of their completed fundamental group.

SUMMARY:Strictly convergent rigid subanalytic sets
DESCRIPTION:Let K be a non-archimedean complete normed field\, K_alg the algebraic closure of K and let L be the language of normed fields augmented with symbols for the strictly convergent powerseries over K. Strictly convergent rigid subanalytic sets over K are the subsets of (K_alg)^n definable in L. I will survey what is known about these sets\, including recent joint results with Raf Cluckers.

SUMMARY:Representations of quasi-projective fundamental groups and the structure of transversely projective foliations
DESCRIPTION:Corlette and Simpson classified Zariski dense rank-two representations of fundamental groups of quasi-projective manifolds under the aditional assumption that the monodromy is quasi-unipotent at infinity. I will explain how to avoid such extra assumption\, and how to obtain a similar classification for singular transversely projective foliations on projective manifolds.

SUMMARY:Newton-Puiseux Theorem for convergent generalised power series
DESCRIPTION:A generalised power series (in several variables) is a series with real nonnegative exponents whose support is contained in a cartesian product of well-ordered subsets of the real line. Let A be the collection of all convergent generalised power series. I will show that\, if f(x_1\,…\,x_n\,y) is in A\, then the solutions y=g(x_1\,…\,x_n) of the equation f=0 can be expressed as terms of the language which has a symbol for every function in A and a symbol for division. The construction of the terms is rather explicit. If instead of solving just one equation one wants to solve a system of equations\, then one needs a different argument and the proof I will exhibit is a lot less constructive.

SUMMARY:NIP\, amenability\, and dynamics
DESCRIPTION:I will discuss problems around definably amenable groups in NIP theories\, informed by some invariants coming from topological dynamics.
