The Chiral Limit of Fully Nonlinear Minimal Massive Gravity
Massimo Porrati, Xilin Sheng
We study 3D Anti de Sitter Minimal Massive Gravity in two regimes: a) at the chiral limit where one of the boundary Brown-Henneaux central charges vanishes and two modes become nul…

Stochastic Stability of Monotone Dynamical Systems. I. The Irreducible Cooperative Systems
Jifa Jiang, Xi Sheng, Yi Wang
The current series of papers is concerned with stochastic stability of monotone dynamical systems by identifying the basic dynamical units that can survive in the presence of noise…

Birkhoff Center and Statistical Behavior of Competitive Dynamical Systems
Xi Sheng, Yi Wang, Yufeng Zhang
We investigate the location and structure of the Birkhoff center for competitive dynamical systems, and give a comprehensive description of recurrence and statistical behavior of o…
