My question is, where could I get some more info on how the Euler-Lagrange equations are related
$$ \delta S [y(x)] =0 $$
with the Feynmann path integral formulation $ \int D[y(X)]e^{iS[y(x)]/\hbar} $
I believe that when $ \hbar \to 0$ (semiclassical), only the points that satisfy (1) contribute to the path integral.
If someone can give me more info about it :D thanks
