comment Equation of motion for cyclic model of the universe
I think that $\triangle\phi$ is zero and $\phi$ only depends on time @Trimok.

comment Equation of motion for cyclic model of the universe
Thanks very much, @Trimok. That explains the factor 4, but what about the sign? I read this article. In this paper the sign of the coupling term is negative. Which one is correct?

@LuboŇ° Motl I read somewhere that these fields cannot be a coordinate basis since the commutator does't vanish (like what we have in QM). But I don't know why.
