Abstract

fetched live from OpenAlex

Let 0 < r < 1/4 , and f be a non-vanishing continuous function in |z|\leq r , that is analytic in the interior. Voronin’s universality theorem asserts that translates of the Riemann zeta function \zeta(3/4 + z + it) can approximate f uniformly in |z| < r to any given precision \varepsilon , and moreover that the set of such t \in [0, T] has measure at least c(\varepsilon) T for some c(\varepsilon) > 0 , once T is large enough. This was refined by Bagchi who showed that the measure of such t \in [0,T] is (c(\varepsilon) + o(1)) T , for all but at most countably many \varepsilon > 0 . Using a completely different approach, we obtain the first effective version of Voronin's Theorem, by showing that in the rate of convergence one can save a small power of the logarithm of T . Our method is flexible, and can be generalized to other L -functions in the t -aspect, as well as to families of L -functions in the conductor aspect.

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.
