Abstract

fetched live from OpenAlex

We consider the nonlinear focusing Klein-Gordon equation in 1 + 1 dimensions and the global space-time dynamics of solutions near the unstable soliton.Our main result is a proof of optimal decay, and local decay, for even perturbations of the static soliton originating from well-prepared initial data belonging to a subset of the stable manifold constructed in [2,24].Our results complement those of Kowalczyk-Martel-Muñoz [24] and confirm numerical results of Bizon-Chmaj-Szpak [3] when considering nonlinearities u p with p ≥ 4. In particular, we provide new information both local and global in space about asymptotically stable perturbations of the soliton under localization assumptions on the data.

Full frame distilled prediction

Teacher imitation

Not 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.
