考虑V(1)谱的同伦群.首先借助May谱序列得到V(2)谱的上同调群的一些结论,然后用代数方法证明了在Adams谱序列中,(b1)^2g1∈ExtA^6,3p^2q+2pq(H*V(1),Zp)是永久循环且不是dr边缘,从而收敛到π3p^2q+2pq-6V(1)中的非零元.
The homotopy group of spectrum V(1) is considered, some conclusions about cohomolopy group of spectrum V(2) are obtained by using May spectral sequences. And then it is proved that (b1)^2g1∈ExtA^6,3p^2q+2pq(H*V(1),Zp) is a permanent cycle and can't be hit by any differential in the Adams spectral sequence by using algebra method, this is to say it converges to a notrivial homotopy element in π3p^2q+2pq-6V(1).
