Large Sets in Countable Amenable Group and its Applications
  In the present paper our main objective is to extend the notion of $D$-sets in countable amenable groups and to discuss its connection with weak mixing for amenable group actions. Further we prove that *-notions are equivalent in the countable amenable group of polynomials generated by finite fields.
