Abstract:
By using new techniques based on the algebraic and geometric Kahn-Priddy theorems, we make new computations of stable homotopy groups of spheres.Based on our computation, together with previous results, we now know spheres of dimensions 1, 2, 3, 5, 6, 12, 56, 61 have unique differential structures. Moreover, all the other odd dimensional spheres has exotic structures.
