Why this work is in the frame

A frame that forgets how it found something cannot be audited. These are the routes that admitted this work.

fundA Canadian funder is recorded on the work.
no affNo Canadian affiliation: this work is invisible to an affiliation-only frame.
No Canadian affiliation. An affiliation-only frame, the usual design, would never have seen this work. It is one of the works that make the case for inverting the frame.

Abstract

fetched live from OpenAlex

For a model with dispersion relation e(k)e(k) and interaction V = 0, the Green's functions are the moments of the Grassmann Gaussian measure, d C(e) , whose covariance is the Fourier transform ofThe interaction between the Fermions is determined by the effective potentialWe assume that V is translation invariant and spin independent.For some results, we also assume that V obeyswhere R 0 (x 0 , x, ) = (-x 0 , x, ) and -(x 0 , x, ) = (-x 0 , -x, ).We call (I.1) "k 0 -reversal reality" and (I.2)"bar/unbar exchange invariance".Precise definitions and a discussion of the properties of these symmetries are given in Appendix B of [FKTo2].In the case of a two-body interaction v(x 0 , x), the interaction kernel iswhere ((x 0 ,x,),(x 0 ,x , )) = (x 0 -x 0 )(x-x ) , .If the Fourier transform, v(k 0 , k), of the two-body interaction v(x 0 , x) obeys v(-k 0 , k) = v(k 0 , k) , then the interaction kernel V has all four symmetries mentioned above.In addition, V always conserves particle number.We briefly discuss the norms imposed on interaction kernels.For a function f (x 1 , , x n ) on (IR IR d {, }) n we define its L 1 -L -norm as |||f ||| 1, = max 1j 0 n sup x j 0 IRIR d {,}

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.
