A note on the comparison between Laplace and Sumudu transforms

In this paper‎, ‎we discuss the existence of double Sumudu transform and‎ ‎study relationships between Laplace and Sumudu transforms‎. ‎Further‎, ‎we apply two transforms to solve linear ordinary‎ ‎differential equations with constant coefficients and non‎ ‎constant coefficients‎.
