- Researchers studying discrete dynamical systems
- Worth noticing
- For listed families, theorem-based answers avoid orbit-following even when the finite field is so large that iteration would take years.
Field notes
Users enter a system and states once; the page says the tool computes Id(s, t) and Q1–Q11 together. Its supported list includes Lyness maps and a discretised Euler top, while unsupported systems are handled by orbit-following only up to a limit. The certificate records assumptions and theorem names as well as the answer, and a separate checker rechecks it from the definitions.
