Abstract

fetched live from OpenAlex

Abstract. The paper investigates how correlations can completely specify a uniformly discrete point process. The setting is that of uniformly discrete point sets in real space for which the corresponding dynamical hull is ergodic. The first result is that all of the essential physical information in such a system is derivable from its n-point correlations, n = 2, 3,.... If the system is pure point diffractive an upper bound on the number of correlations required can be derived from the cycle structure of a graph formed from the dynamical and Bragg spectra. In particular, if the diffraction has no extinctions, then the 2 and 3 point correlations contain all the relevant information. 1. The Setting 1.1. Quasicrystals and dynamical systems. The defining feature of physical cyrstals and quasicrystals is the prominent appearance of Bragg peaks in their diffraction diagrams. Mathematically the diffraction is a positive measure and the Bragg peaks comprise the pure point component of this measure. In a ‘perfect ’ crystal or quasicrystal, the diffraction should be entirely pure point, and that is the situation that we shall assume here. We shall simply refer to these as quasicrystals in the sequel.

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.
