Green's function differential equations
WebThis paper deals with the solutions of linear inhomogeneous time-fractional partial differential equations in applied mathematics and fluid mechanics. The fractional derivatives are described in the Caputo sense. The fractional Green function method is ... WebFeshbach, Methods of Theoretical Physics, 1953 for a discussion of Green’s functions. The Green’s function is used to find the solution of an inhomogeneous differential equation and/or boundary conditions from the solution of the differential equation that is homogeneous everywhere except at one point in the space of the independent variables.
