Oka 和第二作者考虑了第二 Morava 稳定子代数的上同调,以研究球体稳定同伦群的 β 元素乘积的非平凡性。在本文中,我们使用第三 Morava 稳定代数的上同调来求球面稳定同伦群的希腊字母的非平凡积: $\al_1\ga_t$, $\be_2\ga_t$, $\lrk{\al_1,\al_1,\be_{p/p}^p}\ga_t\be_1$ 和$\lrk{\be_1,p,\ga_t}$ 对于 $t$,$p\nmid t(t^2-1)$ 对于素数 $p>5$。
Oka and the second author considered the cohomology of the second Morava stabilizer algebra to study nontriviality of the products of beta elements of the stable homotopy groups of spheres. In this paper, we use the cohomology of the third Morava stabilizer algebra to find nontrivial products of Greek letters of the stable homotopy groups of spheres: $\al_1\ga_t$, $\be_2\ga_t$, $\lrk{\al_1,\al_1,\be_{p/p}^p}\ga_t\be_1$ and $\lrk{\be_1,p,\ga_t}$ for $t$ with $p\nmid t(t^2-1)$ for a prime number $p>5$.
