    Topological resonances on quantum graphs
    We consider metric graphs which consist of a finite graph with someleads attached to some vertices. To this graph is associated a Laplacian using the Kirchoff conditions.We describe some asymptotic properties of the resonances close tothe real axis. This is a joint work with Y. Colin de Verdière.

    Old and new aspects of the Poincaré-Birkhoff-Witt theorem
    The Poincaré-Birkhoff-Witt theorem on universal enveloping algebras of Lie algebras is one of the fundamental results in many areas of mathematics: from differential geometry and representation theory to homological algebra and deformation quantisation. I shall give a short overview of that result and some of its proofs that emerged in about 120 years since Poincaré published a paper about it, and outline a new proof which perhaps captures its category-theoretic essence in the best way possible. The talk is partly based on a joint work with Pedro Tamaroff

    Approach to the equilibrium of a model of rigid structure floating in a viscous fluid.
    In this talk we will study the explicit solutions and the asymptotic behavior of a problem of return to equilibrium in a model of rigid structures floating in a viscous fluid. To present our results, we will briefly study the main asymptotic properties of Mitagg-Leffler functions in two parameters and some new results on dual properties of real Hurwitz-type polynomials. Finally, we will present numerical simulations of the asymptotic results obtained.

    Contractible 3-manifold and Positive scalar curvature
    It is not known whether a contractible 3-manifold admits a complete metric of positive scalar curvature. For example, the Whitehead manifold is a contractible 3-manifold but not homeomorphic to $R^{3}$. In this talk, I will present my proof that it does not have a complete metric with positive scalar curvature. I will further explain that a contractible genus one 3-manifold, a notion introduced by McMillan, does not admit a complete metric of positive scalar curvature.
