摘　　要：In this paper, we concerns the sufficient conditions for the solubility of the mul tiplicative inverse eigenvalue problem. With the help of the topological mapping degree we give some new sufficient conditions, with improve some of de Oliveira’s[2],He Xuchu and Dai Hua’s[3] results.In this paper, we concerns the sufficient conditions for the solubility of the mul tiplicative inverse eigenvalue problem.
