作者： yanpei wang Yuhao CONG Guangda HU Department of Mathematics College of SciencesShanghai UniversityShanghai 200444China Shanghai Customs College Shanghai 201204China

This paper deals with the stability of linear multistep methods for multidimensional differential systems with distributed delays. The delay-dependent stability of linear multistep methods with compound quadrature rules is studied. Several new sufficient criteria of delay-dependent stability are obtained by means of the argument principle. An algorithm is provided to check delay-dependent stability. An example that illustrates the effectiveness of the derived theoretical results is given.
