WebFeb 5, 2012 · And if I recall correctly, a Green's function is used to solve inhomogeneous linear equations, yet Schrodinger's equation is homogeneous $$\left(H-i\hbar\frac{\partial}{\partial t}\right)\psi(x,t) = 0,$$ i.e. there is no forcing term. I do understand that the propagator can be used to solve the wave function from initial conditions (and ...
