Viet-Cuong Pham

摘要:

设$A_1$是一类有限谱中的任意谱,其模$A_1$上同调同构于Steenrod代数的子代数$\mathcal{A}(1)$上的秩为1的自由模.设$E_{C}$是第二Morava-$E$理论,它与定义在$\mathbb{F}_{4}$上的超奇异椭圆曲线$(C) : y^{2}+y = x^{3}$的形式完备化的一个普遍变形有关,$G_{24}$是$C$的形式完备化的自同构群$\mathbb{S}_{C}$的一个极大有限子群.本文利用同伦不动点谱序列计算了$E_{C}^{hG_{24}}\wedge A_1$的同伦群。

英文摘要:

Let $A_1$ be any spectrum in a class of finite spectra whose mod $2$ cohomology is isomorphic to a free module of rank one over the subalgebra $\mathcal{A}(1)$ of the Steenrod algebra. Let $E_{C}$ be the second Morava-$E$ theory associated to a universal deformation of the formal completion of the supersingular elliptic curve $(C) : y^{2}+y = x^{3}$ defined over $\mathbb{F}_{4}$ and $G_{24}$ a maximal finite subgroup of automorphism group $\mathbb{S}_{C}$ of the formal completion of $C$. In this paper, we compute the homotopy groups of $E_{C}^{hG_{24}}\wedge A_1$ by means of the homotopy fixed point spectral sequence.
