Galactic disks as reaction-diffusion systems
Lee Smolin
A model of a galactic disk is presented which extends the homogeneous one zone models by incorporating propagation of material and energy in the disk. For reasonable values of the…
The classical limit and the form of the hamiltonian constraint in nonperturbative quantum gravity
Lee Smolin
It is argued that some approaches to non-perturbative quantum general relativity lack a sensible continuum limit that reproduces general relativity. The basic problem is that gener…
Three Dimensional Strings as Collective Coordinates of Four Dimensional Non-Perturbative Quantum Gravity
Lee Smolin
A string theory in euclidean spacetime dimensions is found to describe the semiclassical behavior of a certain exact physical state of quantum general relativity in dimensi…
Mixmaster quantum cosmology in terms of physical dynamics
Seth Major, Lee Smolin
An approach to quantum cosmology, relying on strengths of both canonical and path integral formalisms, is applied to the cosmological model, Bianchi type IX. Physical quantum state…
