## Abstract

In this naper we describe the properties of the line graph of gamma-acyclic hypergraphs. Based on the properties, an efficient algorithm is given for determining whether a hypergraph is gamma- acyclic. The algorithm runs in O(n(n+e)) time for a hypergraph with its line graph having n vertices and e edges.
