Abstract:This paper proves that, for any generator x ε Ext A s,tq (Z p , Z p ), if (1 L i)*φ*(x) ε Ext A s+1,tq+2q (H*LM,Z p ) is a permanent cycle in the Adams spectral sequence (ASS), then h0x ε Ext A s+1,tq+q (Z p , Z p ) also is a permenent cycle in the ASS. As an application, the paper obtains that h 0 h n h m $$
Ext_A^{3,p^n q + p^m q + q} (Z_p ,Z_p )
$$ is a permanent cycle in the ASS and it converges to elements of order p in the stable homotopy groups of spheres $$
\pi _{p^n q + p^m q + q - 3} S
$$, where p ≥ 5 is a prime, s ≤ 4, nm+2 ≥ 4 and M is the Moore spectrum. Supported by NSFC No. 10171049
