Abstract

fetched live from OpenAlex

In this note we calculate the variation of the Rayleigh quotient under specific variations of the metric. We consider two cases. First we study conformal variations and secondly variations within a Kähler class. We use the first variational formula to reprove an important result of Uhlenbeck’s: a generic metric can be perturbed by a conformal factor into a metric whose eigenspaces for the Laplace operator have dimension <inline-formula content-type="math/mathml"> <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" alttext="1"> <mml:semantics> <mml:mn>1</mml:mn> <mml:annotation encoding="application/x-tex">1</mml:annotation> </mml:semantics> </mml:math> </inline-formula> . In the case of a Kähler manifold, we write an explicit variational formula for the Rayleigh quotient under Kähler deformations. We relate our calculation with the following question: Is the spectrum of a generic Kähler metric simple?

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.
