The Hartle-Hawking wave function in 2d causal set quantum gravity
Lisa Glaser, Sumati Surya
We define the Hartle-Hawking no-boundary wave function for causal set theory (CST) over the discrete analogs of spacelike hypersurfaces. Using Markov Chain Monte Carlo and numerica…

Endeavours in Discrete Lorentzian Geometry; A thesis in five papers
Lisa Glaser
To solve the path integral for quantum gravity, one needs to regularise the space-times that are summed over. This regularisation usually is a discretisation, which makes it necess…
