Abstract
In the paper, we develop a new method of combining the singular limit argument and the singular perturbation technique to establish the existence of the point-to-periodic heteroclinic travelling wave solutions connecting an equilibrium and a periodic travelling wave solution for a delayed predator–prey diffusion partial differential equation (PDE) system. The model is a very important delayed prey–predator diffusion PDE system, which is used to describe the spatiotemperal dynamics in many biology communities. The study of existence of point-to-periodic travelling waves for this delayed PDE system is important and challenging. We strictly prove that with large wave speeds, the point-to-periodic heteroclinic travelling waves exist for small delay. We also prove the existence of the periodic travelling wave solutions for small delay and the existence of the point-to-point heteroclinic travelling wave solutions connecting two equilibria for any delay.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
