Galois Trace

When doing Inter-Correlational analysis between different traces and logs, we can move simultaneously along time direction or backward (Back Tracing). In some cases, we may start our analysis with the identification of Significant Events in both logs and then move in opposite directions finding another pair of messages that can be useful for diagnostic identification. We call this analysis pattern Galois Trace by analogy with Galois connection64 in mathematics. In our case moving from trace A to trace B and back corresponds to F and G functions with a and b as individual trace messages or their Message Contexts (as per monotone65 definition). The analysis pattern is illustrated in the following diagram:
