Introduction to causal sets: an alternate view of spacetime structure
arXiv:gr-qc/9909075 · doi:10.1139/cjp-79-1-1
Abstract
This paper provides a thorough introduction to the causal set hypothesis aimed at students, and other interested persons, with some knowledge of general relativity and nonrelativistic quantum mechanics. I elucidate the arguments for why the causal set structure might be the appropriate structure for a theory of quantum gravity. The logical and formal development of a causal set theory as well as a few illuminating examples are also provided.
