| Abstract: | This paper discusses the lower generalized exponent set for the class of primitive digraphs. It shows that the maximum value of the k th lower generalized exponent of primitive digraph of order n(≥3) with girth 2 is n-k(2≤k≤n), and gives a complete characterization for the exponent set. |

| Keywords: | girth primitive digraph exponent the lower generalized exponent |
