%0 Journal Article %T Secondary Brown-Kervaire Quadratic forms and $¦Ð$-manifolds %A Fuquan Fang %A Jianzhong Pan %J Mathematics %D 2001 %I arXiv %X In this paper we define a secondary Brown-Kervaire quadratic forms. Among the applications we obtain a complete classification of (n-2)-connected 2n-dimensional framed manifolds up to homeomorphism and homotopy equivalence, . In particular, we prove that the homotopy type of such manifolds determine their homeomorphism type. %U http://arxiv.org/abs/math/0106256v1
