we all know that given a differential equation Ly=a0(x)y+a1(x)Dy+a2(x)D^2y=0 with Dy=dy/dx we can construct a Green function so LG(x,s)=d(x-s) being d the delta function.(adsbygoogle = window.adsbygoogle || []).push({});

My question is this given the G(x,s) could we construct the L so LG(x,s)=d(x-s) could someone provide an example of how to obtain?..thanks.
