Publications Erratum to " The local lifting problem for actions of finite groups on curves''... Annales Scientifiques de l'École Normale Supérieure Résumé : We correct Theorem1.5 in our paper " The local lifting problem for actions of finite groups on curves,'' Ann. Sci. Éc. Norm. Supér. (4) 44 (2011), 537--605.
Publications Hecke Actions on Loops and Periods of Iterated Shimura Integrals... Annales Scientifiques de l'École Normale Supérieure Résumé : We show that the classical Hecke correspondences $T_N$ act on the free abelian group generated by the conjugacy classes of the modular group $SL_2(Z)$ and the conjugacy classes of its p...
Publications A degenerate Arnold diffusion mechanism in the restricted 3-body problem... Annales Scientifiques de l'École Normale Supérieure Résumé : A major question in dynamical systems is to understand the mechanisms driving global instability in the 3-body problem (3BP), which models the motion of three bodies under Newtonian gr...
Publications An obstruction to the local lifting problem... Annales Scientifiques de l'École Normale Supérieure Résumé : We are investigating the lifting problem for local actions involving semidirect products of a cyclic $p$-group with a cyclic group prime to $p$, where $p$ represents the characteristic ...
Publications Topology of irrationally indifferent attractors... Annales Scientifiques de l'École Normale Supérieure Résumé : We study the post-critical set of a class of holomorphic maps with an irrationally indifferent fixed point. We prove a trichotomy for the topology of the post-critical set based on the ...
