1307.4687 (Jedrzej Świeżewski)

Comment on "Time and a Physical Hamiltonian for Quantum Gravity"    [PDF]

Jedrzej Świeżewski
The aim of this comment is to present a simple argument showing that in the irrotational dust model the Hamilotnian constraint is indeed free of the square root if the time-gauge is chosen. This feature requires no additional assumptions, namely no choices of signs.
