Web308 Permanent Redirect WebJun 5, 2012 · Green's functions permit us to express the solution of a non-homogeneous linear problem in terms of an integral operator of which they are the kernel. We have already presented in simple terms this idea in §2.4. We now give a more detailed theory with applications mainly to ordinary differential equations.
WebSimilarly, on (ξ,b] the Green’s function must be proportional to y2(x) and so we set G(x,ξ)=B(ξ)y2(x) for x ∈ 9ξ,b]. (7.6) Note that the coefficient functions A(ξ) and B(ξ) may depend on the point ξ, but must be independent of x. This construction gives us families of Green’s function for x ∈ [a,b] −{ξ}, in terms of the ...
