A State Sum Model for (2+1) Lorentzian Quantum Gravity
Stefan Davids
A state sum model based on the group SU(1,1) is defined. Investigations of its geometry and asymptotics suggest it is a good candidate for modelling (2+1) Lorentzian quantum gravit…

Semiclassical Limits of Extended Racah Coefficients
Stefan Davids
We explore the geometry and asymptotics of extended Racah coeffecients. The extension is shown to have a simple relationship to the Racah coefficients for the positive discrete uni…
