Here first, second order linear inhomogeneous differential equations are considered and then we extend it to the nth order. Green’s function plays a great role for solving such differential equations. Classical theory is based on solving first- or higher-order derivatives with jumps on both sides of the boundaries and then attempting to satisfy the boundary conditions. Our aim is to develop the vector analysis of functions with jump discontinuities across surfaces and boundaries that cannot be solved by classical techniques. With the help of this we can solve many unsolved problems in the potential, scattering and wave propagation theories. Furthermore, problems whose solutions are already known can be solved by this method in a very simple fashion. We can also show that there is a new solution of linear homogeneous systems of differential equations with singular in coefficients, in the space of generalized functions other than the classical solutionsenGeneralized Solutions of BoundaryValue Problems With Jump DiscontinuityThesis
