| Abstract: | First the article obtain some necessary conditions for the existence of relative difference sets.Then it generalize near difference sets of type 2 to Abel near difference sets of type 2,and obtain some necessary conditions for the existence of Abel near difference sets of type 2.These conclusions are the generalizations of some known results about difference sets and near difference sets. |

| Keywords: | difference sets relative difference sets near difference sets Abel near difference sets of type 2 Hall polynomial |
