摘要:

对于每一个素数$p$,我们在$\widehat{S^{0,0}}/τ$上的调和$\mathbb{C}$ -模左模谱范畴$\widehat{S^{0,0}}/τ\text{-}\mathbf{Mod}_{harm}^b$上定义了一个$t$ -结构,它的MGL-同调具有有界的Chow-Novikov度,使得它的心等价于集中在偶数度上的$p$ -完备$BP_*BP$ -余模的阿贝尔范畴.我们证明了$\widehat{S^{0,0}}/τ\text{-}\mathbf{Mod}_{harm}^b$等价于$\mathcal{D}^b({{BP}_*{BP}\text{-}\mathbf{Comod}}^{ev})$作为稳定的$\infty$ -范畴,它具有$t$ -结构.作为应用,对每个素数$p$,我们证明了$\widehat{S^{0,0}}/τ$的模Adams谱序列与代数Novikov谱序列同构,前者收敛于$\widehat{S^{0,0}}/τ$的模同伦群,后者收敛于经典的球谱$\widehat{S^0}$的Adams-Novikov $E_2$ -page.这种谱序列的同构允许Isaksen和第二和第三作者计算稳定的同伦群的领域至少90茎,与正在进行的计算到更高的维度。

英文摘要:

For each prime $p$, we define a $t$-structure on the category $\widehat{S^{0,0}}/τ\text{-}\mathbf{Mod}_{harm}^b$ of harmonic $\mathbb{C}$-motivic left module spectra over $\widehat{S^{0,0}}/τ$, whose MGL-homology has bounded Chow-Novikov degree, such that its heart is equivalent to the abelian category of $p$-completed $BP_*BP$-comodules that are concentrated in even degrees. We prove that $\widehat{S^{0,0}}/τ\text{-}\mathbf{Mod}_{harm}^b$ is equivalent to $\mathcal{D}^b({{BP}_*{BP}\text{-}\mathbf{Comod}}^{ev})$ as stable $\infty$-categories equipped with $t$-structures. As an application, for each prime $p$, we prove that the motivic Adams spectral sequence for $\widehat{S^{0,0}}/τ$, which converges to the motivic homotopy groups of $\widehat{S^{0,0}}/τ$, is isomorphic to the algebraic Novikov spectral sequence, which converges to the classical Adams-Novikov $E_2$-page for the sphere spectrum $\widehat{S^0}$. This isomorphism of spectral sequences allows Isaksen and the second and third authors to compute the stable homotopy groups of spheres at least to the 90-stem, with ongoing computations into even higher dimensions.
