原始语种摘要: In this article we establish a version of Koszul duality for filtered rings arising from $ p$-adic Lie groups. Our precise setup is the following. We let $ G$ be a uniform pro-$ p$ group and consider its completed group algebra $ \Omega =k\llbracket G\rrbracket $ with coefficients in a finite field $ k$ of characteristic $ p$. It is known that $ \Omega $ carries a natural filtration and $ \text {gr} \Omega =S(\frak {g})$ where $ \frak {g}$ is the (abelian) Lie algebra of $ G$ over $ k$. One of our main results in this paper is that the Koszul dual $ \text {gr} \Omega ^!=\bigwedge \frak {g}^{\vee }$ can be promoted to an $ A_{\infty }$-algebra in such a way that the derived category of pseudocompact $ \Omega $-modules $ D(\Omega )$ becomes equivalent to the derived category of strictly...
