WebApr 30, 2024 · The Green’s function concept is based on the principle of superposition. The motion of the oscillator is induced by the driving force, but the value of x(t) at time t does not depend only on the instantaneous value of f(t) at time t; instead, it depends on the values of f(t ′) over all past times t ′ < t. 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 ...
