Abstract

fetched live from OpenAlex

In this paper, long-time and high-order moment asymptotics for super-Brownian motions (sBm’s) are studied. By using a moment formula for sBm’s (e.g. (Ann. Appl. Probab. 33 (2023) 3872–3915, Theorem 3.1)), precise upper and lower bounds for all positive integer moments at any time t > 0 of sBm’s for certain initial conditions are achieved. Then, the moment asymptotics as time goes to infinity or as the moment order goes to infinity follow immediately. Additionally, as an application of the two-sided moment bounds, the tail probability estimates of sBm’s are obtained.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
