设p≥7为任意奇素数, A为模p的Steenrod代数. 1962年, A. Liulevicius在他的文章中指出元素hi, bk∈Ext*A(Zp, Zp)分别具有双次数(1, 2pi(p8722;1))和(2, 2pk+1(p8722;1)). 我们证明: 当p≥7, n≥4, 3≤s<p8722;1时, 积h0hn-1rs ∈ ExtAs+3,p+sp2q+(s-1)pq+(s-1)q+s-3(Zp,Zp)收敛到Z∞, 其中q=2(p8722;1). 相似文献

In this paper, the authors introduce a new effective method to compute the generators of the E1-term of the May spectral sequence. This helps them to obtain four families of non-trivial product elements in the stable homotopy groups of spheres. 相似文献

Let A be the mod p Steenrod algebra and S be the sphere spectrum localized at an odd prime p. To determine the stable homotopy groups of spheres π*S is one of the central problems in homotopy theory. This paper constructs a new nontrivial family of homotopy elements in the stable homotopy groups of spheres πp^nq+2pq+q-3S which isof order p and is represented by kohn ∈ ExtA^3,P^nq+2pq+q(Zp,Zp) in the Adams spectral sequence, wherep 〉 5 is an odd prime, n ≥3 and q = 2(p-1). In the course of the proof, a new family of homotopy elements in πp^nq+(p+1)q-1V(1) which is represented by β*i'*i*(hn) ∈ ExtA^2,pnq+(p+1)q+1 (H^*V(1), Zp) in the Adams sequence is detected. 相似文献

Let p be an odd prime. The authors detect a nontrivial element ã p of order p2 in the stable homotopy groups of spheres by the classical Adams spectral sequence. It is represented by \(a_0^{p - 2} h_1 \in Ext_A^{p - 1,pq + p - 2} (\mathbb{Z}/p,\mathbb{Z}/p)\) in the E2-term of the ASS and meanwhile p · ã p is the first periodic element α p . 相似文献

Abstract This paper computes the Thom map on γ2 and proves that it is represented by 2b2,0h1,2 in the ASS. The authors also compute the higher May differential of b2,0, from which it is proved that
for 2 ≤ s < p - 1 are permanent cycles in the ASS.
