Title: Higher curvature terms for Causal Sets

Abstract:
Causal Sets is a Quantum Gravity theory which postulates space-time to be emergent from partially ordered sets. The order encodes the causality relations between the elements, which can be understood as space-time points. To understand how a discrete causal set encodes the geometry of space-time and how space-time emerges from fundamental causal sets, it is important to be able to calculate curvature perators intrinsically from their causal order.

In my thesis I examined an operator on Causal Sets which contains the Ricci-scalar in its continuum limit. From there a new operator will be introduced that contains both the square and the d'Alembertian of the Ricci-scalar in its limit and results from simulations with both operators will be shown.
