Abstract

fetched live from OpenAlex

Abstract We find the necessary and sufficient conditions for a free convolution $\mu \boxtimes \nu $ to have an analytic and positive density, where $\mu $ is $\boxtimes $-infinitely divisible. If the density of $\mu \boxtimes \nu $ vanishes at some points, we also study the analyticity of this density at such zeros. Finally, we show that $\mu \boxtimes \nu $ has a finite number of connected components in its support if both the free Lévy measure of $\mu $ and the measure $\nu $ do. These results are applied to multiplicative free Lévy processes on the positive line and the unit circle.

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.
