形式流形:基础理论

Formal manifolds: foundations

Fulin Chen, Binyong Sun, Chuyun Wang

AI总结:

本文作为系列研究首篇,受代数几何形式概形启发在微分几何中引入形式流形概念,构建其基本理论,建立到拓扑$\text{C}$-代数的完全忠实反变函子,并证明该范畴有限积存在,为相对李代数同调上同调研究奠基。

摘要:

本文是基于形式流形与形式李群理论研究光滑相对李代数同调与上同调的系列论文的首篇。受代数几何中形式概形概念的启发,我们在微分几何语境下引入形式流形的概念,为该研究奠定基础。我们构建了形式流形的基本理论,并建立了从形式流形范畴到拓扑$\boldsymbol{\text{C}}$-代数范畴的完全忠实反变函子。我们还通过研究向量值形式函数,证明了形式流形范畴中有限积的存在性。

英文摘要:

This is the first paper in a series that studies smooth relative Lie algebra homologies and cohomologies based on the theory of formal manifolds and formal Lie groups. In this paper, we lay the foundations for this study by introducing the notion of formal manifolds in the context of differential geometry, inspired by the notion of formal schemes in algebraic geometry. We develop the basic theory for formal manifolds, and establish a fully faithful contravariant functor from the category of formal manifolds to the category of topological $\mathbb{C}$-algebras. We also prove the existence of finite products in the category of formal manifolds by studying vector-valued formal functions.
