Let G be a graph. We say that a hypergraphis a Berge-G if there is a bijectionsuch thatfor all. For any r-uniform hypergraph H and a real number, the-spectral radius  of H is defined as

In this talk, we study the p-spectral radius of Berge-G hypergraphs. We determine the 3-uniform hypergraphs with maximum p-spectral radius foramong Berge-G hypergraphs when G is a path, a cycle, a star or , where  is the set of graphs of order  obtained from  by adding an edge between two non-adjacent vertices.
