SUMMARY
The discussion centers on the avoidance of Ostrogradski instability in modified gravity theories, specifically f(R) theory. It highlights the significance of Woodard's 2007 paper (Lect. Notes. Phys. 720, 403) as a foundational reference, although it only provides a brief overview. Participants seek a more rigorous mathematical explanation of how f(R) theory circumvents this instability. The consensus indicates a need for deeper mathematical insights into the mechanisms at play within f(R) gravity models.
