Lie pairs and formal Lie groups
Fulin Chen, Binyong Sun, Chuyun Wang
In a previous paper, we introduce and study formal manifolds, which generalize smooth manifolds. In this paper, we establish the basic theory of formal Lie groups, which are group…

Intrinsic pressure as a convenient mechanical framework for dry active matter
Zihao Sun, Longfei Li, Chuyun Wang +6
The identification of local pressure in active matter systems remains a subject of considerable debate. Through theoretical calculations and extensive simulations of various active…

Formal manifolds: local structure of morphisms, and formal submanifolds
Fulin Chen, Binyong Sun, Chuyun Wang
This is a 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 three previous pa…
