    • Dynamical Cubes And A Criteria For Systems Having Product Extensions 
      Donoso Fuentes, Sebastián; Sun, Wenbo (Amer Inst Mathematical Sciences-Aims, 2015)
      ABSTRACT. For minimal Z 2 -topological dynamical systems, we introduce a cube structure and a variation of the usual regional proximality relation for Z 2 actions, which allow us to characterize product systems and ...
    • Seminorms for multiple averages along polynomials and applications to joint ergodicity 
      Donoso Fuentes, Sebastián Andrés; Koutsogiannis, Andreas; Sun, Wenbo (Hebrew Univ. Magnes, Israel, 2021)
      Exploiting the recent work of Tao and Ziegler on the concatenation theorem on factors, we find explicit characteristic factors for multiple averages along polynomials on systems with commuting transformations, and use them ...
