We have for Quantum gravity the equation:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]H|\Psi>=0 [/tex] as you can see this is time-independent partial differential equation, my question is if we could construct a functional differential equation in the form:

[tex]\alpha{d\Psi/dt}+\Beta{H_1}=0 [/tex] where the H1 would have the derivatives respect to the metric and alpha and beta would be matrices (alpah is a Grassman number) in a way that we would have a functional equation of spin 2 (graviton) with this we would have solved the problem of time in quantum gravity.
