fermatslibrary.com - interesting academic papers

Useful Resource: http://fermatslibrary.com/

"Fermat’s Library is a platform for illuminating academic papers. Just as Pierre de Fermat scribbled his famous last theorem in the margins, professional scientists, academics and citizen scientists can annotate equations, figures and ideas and also write in the margins. Every week we send you a new paper annotated by the community."

Wheeler-DeWitt equation


http://en.wikipedia.org/wiki/Wheeler%E2%80%93DeWitt_equation
The Wheeler–DeWitt equation[1] is an attempt to mathematically meld the ideas of quantum mechanics and general relativity, a step toward a theory of quantum gravity. In this approach, time plays no role in the equation, leading to the problem of time.[2] More specifically, the equation describes the quantum version of the Hamiltonian constraint using metric variables. Its commutation relations with the diffeomorphism constraints generate the Bergmann-Komar "group" (which is the diffeomorphism group on-shell, but differs off-shell).
