Résumé: 
Topologie algébrique  On $v_1$periodic motivic stable homotopy groups of spheres  
Description: 
J. D. QuigleyIn the 1960's, Adams computed the image of the Jhomomorphism in the stable homotopy groups and related it to special values of the Riemann zeta function. In this talk, I will discuss work computing the "motivic imageofJ" over prime fields and its applications to understanding periodic phenomena in the motivic stable homotopy groups of spheres over arbitrary base fields. I will also discuss workinprogress extending these results over rings of integers of number fields, along with possible connections to special values of Dedekind zeta functions. This is joint work with Hana Jia Kong.
