Action In Causal Set Theory, Santosh Bhandari

Electronic Theses and Dissertations

The aim of this thesis is to explore causal set theory (CST), which proposes that at the smallest level of spacetime, discrete entities known as “spacetime atoms” are causally related to one another, forming the basis for understanding quantum gravity. While theories such as general relativity that operate on a continuous manifold are more appropriate when dealing with the universe on a large scale, it is crucial for the discrete causal points in CST to maintain their causal structure during the continuum approximation to ensure consistency with general relativity. One way to preserve the causal structure is to accurately embed …
