Chronology violation on locally finite quasiordered sets

Author(s): Othman Echi
Classical causal set theory models spacetime causality by locally finite partial orders. Because partial orders are antisymmetric, they cannot represent distinct elements that are mutually causally related, as would occur in a discrete analogue of a chronology-violating region. We develop a locally …
