If time had no beginning: growth dynamics for past-infinite causal sets

Abstract We explore whether the growth dynamics paradigm of causal set theory is compatible with past-infinite sets. modify classical sequential Rideout and Sorkin to accommodate ‘into past’ discuss what form physical constraints such as causality could take in this new framework. propose convex-suborders ‘observables’ or ‘physical properties’ a which sets can be use proposal construct manifestly covariant framework for dynamical models
