Completeness and incompleteness of trace-based network proof systems
Jennifer Widom, David Gries, F.B. Schneider · 1987
Abstract. Most trace-based proof systems for networks of processes are known to be incomplete. Extensions to achieve completeness are generally complicated and cumbersome. In this paper, a simple trace logic is defined and two examples are presented to show its inherent incompleteness. Surprisingly, both examples consist of only one process, indicating that network composition is not a cause of incompleteness. Axioms necessary and sufficient for the relative completeness of a trace logic are then presented.
