Sometimes we see a constantly repeated message throughout a trace or log (a trivial Periodic Message Block) with constant Time Delta. In certain trace forms (without explicit timing information) such messages may indicate internal time references as illustrated in the following diagram:
We name this pattern Drone Message based on analogy with Drone effect in music.

Based on a mathematical analogy with critical points in topology (Morse theory) we introduce Critical Points in trace and log analysis where they signify the change of trace or log “shape” (topological or “geometric” properties) as illustrated in the following diagram:
Such a point may be an individual message, its Message Context, or Activity Region.
Critical Points are examples of Intra-Correlation whereas Bifurcation Points are examples of Inter-Correlation.
