Green function neumann boundary

WebHowever, for some functions f(x) there is a solution (in fact in nitely many solutions). So the question becomes, is there a way to use some sort of Green’s Function to nd this class of solutions? The answer is yes, we can use a generalized Green’s Function. Let L[˚ h] = 0 for non-trivial function ˚ h (satisfying the appropriate boundary ... WebThe problem for determining the Green’s function is now very concrete, and simply uses el-ementary ODE techniques. First, (12) and (13) are solved separately. Then the general solution to (12) must be made to satisfy the right-hand boundary conditions only, whereas the solution to (13) must satisfy the left-hand boundary conditions.
