Abstract: The moduli space of flat connections on a surface naturally carries a Poisson structure, which can be seen as induced by the intersection of loops on the surface. Also taking self-intersections of loops into consideration one can define the Goldman-Turaev Lie bialgebra structure on the space of loops. On a genus zero surface with three boundary components the linearization problem of this structure is equivalent to the Kashiwara-Vergne problem. Motivated by this result a generalization of the Kashiwara-Vergne problem in higher genera is proposed and solutions are constructed in analogy with elliptic associators. This is joint work with Anton Alekseev, Nariya Kawazumi and Yusuke Kuno.
