Abstract

fetched live from OpenAlex

In this article, we study the stochastic wave equation on the entire space R d , driven by a space-time Lvy white noise with possibly infinite variance (such as the -stable Lvy noise).In this equation, the noise is multiplied by a Lipschitz function (u) of the solution.We assume that the spatial dimension is d = 1 or d = 2.Under general conditions on the Lvy measure of the noise, we prove the existence of the solution, and we show that, as a function-valued process, the solution has a cdlg modification in the local fractional Sobolev space of order r < 1/4 if d = 1, respectively r < -1 if d = 2.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
