Let be L(Y)=a0(x)D^2y+a1(x)Dy+a2(x) with the boundary conditions Y(a)=c and Y(b)=d then we could construct the Green function L(y)G(x,s)=d(x-s) then my question is if given the G(x,s) we could construct the L(y) operator considering is a second order differential equation.
Si si que lo soy,vivo un poco mas al norte que tu (Pais Vasco)..¿que tal? la verdad es que no somos muchos por aqui cierto?..
Hello Integrate the 2 members of L(y)G(x,s)=d(x-s) Then use the formula of inverse Green Function and use the theory of distributions
i did not understand you Feynmann..could you be more explicit if G(x,s) is the Kernel i have that a0(x)D^2G(x,s)+a1(x)DG(x,s)+a2(x)=d(x-s) but i do not know the functions a0(x),a1(x),a2(x) what is the formula of the inverse Green function?....
