Abstract

fetched live from OpenAlex

We study the rate of growth of ergodic sums along a sequence (a_n) of times: S_N f(x)=f(T^{a_1}x) + ... + f(T^{a_N}x). We characterize the maximal rate of growth of these ergodic sums and identify a number of sequences such as (2^n) that achieve this rate of growth. We also return to Khintchine's strong uniform distribution Conjecture which stated that the averages (1/N)(f(x)+f(2x mod 1)+...+f(Nx mod 1)) converge pointwise almost everywhere to \int f for an integrable function on [0,1). We give an elementary counterexample to this conjecture, showing that divergence occurs at the maximal rate. In addition, we consider versions of Khintchine's conjecture in which the sequence of positive integers is replaced by the increasing enumeration of a subsemigroup of the positive integers. We give necessary and sufficient conditions on the semigroup for convergence in the modified 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.
