题目：The last Kervaire invariant problem

摘要：The Kervaire invariant is the obstruction for a framed cobordism class to have a homotopy sphere. It is important to know if this invariant is non-trivial when classifying homotopy spheres in a given dimension. We will give an account on recent joint work with Lin and Xu solving the last case of the Kervaire invariant problem in dimension 126.
