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 J-homomorphism 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 image-of-J" 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 work-in-progress 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. |
