On double Natural transform and its applications

In this work, we generalize the concept of one dimensional Natural transform to two dimensional Natural transform namely, double Natural transform and some of its properties are given. We also set a relation between double Natural transform and double Laplace, double Sumudu transforms. Further the convolution theorem with a proof is investigated with some details. Double Natural transform is applied to get the solutions of some general linear telegraphs, wave and partial integro-differential equations.
