• Almost Periodically Forced Circle Flows 

      Huang, Wen; Yi, Yingfei (Georgia Institute of Technology, 2007)
      We study general dynamical and topological behaviors of minimal sets in skew-product circle flows in both continuous and discrete settings, with particular attentions paying to almost periodically forced circle flows. ...
    • On Almost Automorphic Oscillations 

      Yi, Yingfei (Georgia Institute of Technology, 2003)
      Almost automorphic dynamics have been given a notable amount of attention in recent years with respect to the study of almost periodically forced monotone systems. There are solid evidences that these types of dynamics ...
