摘要
设 p ≥ 7 p \geq 7 是一个素数。让 S ( 3 ) S(3) 表示第三个莫拉瓦稳定器代数。近年来,Kato-Shimomura 和 Gu-Wang-Wu 利用 H ∗ , ∗ ( S ( 3 ) 发现了球体稳定同调环 π ∗ ( S ) \pi _* (S) 中的几个非小乘积族。) H^{*,*} (S(3)) 。在本文中,我们确定了希腊字母族元素 α s , β s , γ s \alpha _s, \beta _s, \gamma _s和科恩元素 ζ n \zeta _n 在 π ∗ ( S ) \pi _* (S) 中的所有非小乘积,这些乘积都可以用 H ∗ , ∗ ( S ( 3 ) ) 检测到。 H^{*,*} (S(3)) 。特别是,我们证明 β 1 γ s ζ n ≠ 0 ∈ π∗ ( S ) \beta _1 \gamma _s \zeta _n \neq 0 \in \pi _*(S),如果 n ≡ 2 n \equiv 2 mod 3, s ≢ 0 , ± 1 s \not \equiv 0, \pm 1 mod p p 。
Detecting nontrivial products in the stable homotopy ring of spheres via the third Morava stabilizer algebra
Let p≥7p \geq 7 be a prime number. Let S(3)S(3) denote the third Morava stabilizer algebra. In recent years, Kato-Shimomura and Gu-Wang-Wu found several families of nontrivial products in the stable homotopy ring of spheres π∗(S)\pi _* (S) using H∗,∗(S(3))H^{*,*} (S(3)). In this paper, we determine all nontrivial products in π∗(S)\pi _* (S) of the Greek letter family elements αs,βs,γs\alpha _s, \beta _s, \gamma _s and Cohen’s elements ζn\zeta _n which are detectable by H∗,∗(S(3))H^{*,*} (S(3)). In particular, we show β1γsζn≠0∈π∗(S)\beta _1 \gamma _s \zeta _n \neq 0 \in \pi _*(S), if n≡2n \equiv 2 mod 3, s≢0,±1s \not \equiv 0, \pm 1 mod pp.
