Abstract

fetched live from OpenAlex

Abstract We study statistical properties of Fourier coefficients of automorphic forms on $\textrm{GL}(n)$. For most Hecke–Maass cusp forms, we give the asymptotic number of nonvanishing coefficients, show that there is a positive proportion of sign changes among them when these are real, and describe the asymptotic density of these signs. We generalize the results of Jääsaari obtained in the case of self-dual forms on $\textrm{GL}(3)$ to almost all forms on $\textrm{GL}(n),$ and our method moreover circumvents the assumption of the Generalized Ramanujan Conjecture.

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.
