Existence of positive solutions has been studied by A. Babakhani and V. Daftardar-Gejji (2003) in caseof multiterm nonautonomous fractional differential equations with constantcoefficients. In the present paper we discuss existence of positive solutions incase of multiterm fractional differential equations of finite delay with polynomialcoefficients.
