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 ... WebWe can now show that an L2 space is a Hilbert space. Theorem 2.3. For p>1, an Lpspace is a Hilbert Space only when p= 2. Proof : We see that the inner product, < x;y >= P 1 n=1 x ny n has a metric; d(x;y) = kx yk 2 = X1 n=1 jx n y nj 2! 1 2 This agrees with the de nition of an Lp space when p= 2. An L2 space is closed and therefore complete, so it follows that an …
