Abstract

fetched live from OpenAlex

By taking the viewpoint of Brownian additive functionals, we extend an existing approximation theorem of the two-dimensional Laplacian singularly perturbed at the origin. The approximate operators are defined by adding a rescaled function to the two-dimensional Laplacian such that the support of the perturbation thus produced converges to a point in the limit of the rescaling, and suitable renormalizations of the coupling constants are also imposed. The first main theorem assumes the zero total mass of the function for rescaling. It proves the limits of the approximate resolvents up to an extended criticality defined by two levels of phase transitions. The second main theorem handles the case of positive total mass of the function for rescaling and proves an asymptotic expansion of a multivariate density induced by the approximate resolvent. Moreover, this expansion is valid beyond criticality.

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.
