摘要

XX为有限型单连通有理椭圆CW复形,具有Sullivan极小模型(ΛV,d)(\Lambda V, d),并设k2k\geq 2为使得d=ikdid=\sum_{i\geq k}d_idi(V)ΛiVd_i(V)\subseteq \Lambda ^iV的最大整数。我们证明:cat(XQ)=depht(ΛV,dk)cat(X_{\mathbb{Q}}) = depht(\Lambda V, d_k)当且仅当(ΛV,dk)(\Lambda V,d_{k})是椭圆的。这一结果通过引入两个新的谱序列得到,这两个谱序列推广了Milnor-Moore谱序列及其Ext\mathcal{E}xt版本\cite{Mur94}。作为推论,我们恢复了由L. Lechuga和A. Murillo在\cite{LM02}以及G. Lupton在\cite{Lup02}中用不同方法证明的一个已知结果:如果(ΛV,dk)(\Lambda V,d_{k})是椭圆的,则cat(XQ)=dim(πodd(X)Q)+(k2)dim(πeven(X)Q)cat(X_{\mathbb{Q}}) = dim(\pi_{odd}(X)\otimes\mathbb{Q}) + (k-2)dim(\pi_{even}(X)\otimes\mathbb{Q})。在域IK{IK}char(IK)=pchar({IK})=p(奇素数)的情况下,我们获得了eIK(X)e_{IK}(X)的代数方法,其中XXrr-连通(r1r\geq 1)的有限CW复形,且p>dim(X)/rp> dim(X)/r
