Impact of chaos on a system's entropy

Click For Summary
SUMMARY

The discussion centers on the relationship between chaos and entropy in dynamical systems. It establishes that as a system transitions from periodic behavior to chaotic behavior, the occupied volume of phase space increases, which correlates with an increase in entropy. The conversation also raises questions about the distinction between fine-grained and coarse-grained entropy, suggesting that while chaos typically leads to increased entropy, there may be exceptions worth exploring.

From a heuristic standpoint it makes sense that when a system goes from being periodic to chaotic, the occupied volume of the phase space increases (while not violating liouville theorem). Since the volume of phase space is proportional if not equal to the entropy, shouldn’t entropy always increase when a system becomes chaotic? Are there counter examples to this?
