 Suspension Homotopy of 4-manifolds And the Second 2-local Cohomotopy Sets

 点: 腾讯会议:6965463074

  要:In this talk we study the homotopy type of the (double) suspension of an orientable, closed, connected 4-manifold M, whose integral homology can have 2-torsion. Moreover, the decomposition results are applied to give a partial characterization of the second 2-local cohomotopy set of 4-manifolds.
