Birkhoff center and recurrent behavior of differentially positive systems on a homogeneous space
Lin Niu, Yi Wang, Yufeng Zhang
We study the structure of the Birkhoff center and the recurrent behavior of differentially positive systems whose linearizations along trajectories preserve a homogeneous cone fiel…
Rigidity and Galois theory of 3-manifolds branched over Chebotarev links
Nadav Gropper, Jun Ueki, Yi Wang
The classical Neukirch--Uchida theorem states that the absolute Galois group determines a number field up to isomorphism. We prove an analogue of this theorem for 3-manifolds in th…
Almost sure convergence of differentially positive systems on a globally orderable manifold
Lin Niu, Yi Wang, Yufeng Zhang
Differentially positive systems are nonlinear systems whose linearization along trajectories preserves a cone field on a smooth Riemannian manifold. The structures of cone field co…
Generic behavior of differentially positive systems on a globally orderable Riemannian manifold
Lin Niu, Yi Wang
Differentially positive systems are the nonlinear systems whose linearization along trajectories preserves a cone field on a smooth Riemannian manifold. One of the embryonic forms…
