Abstract

fetched live from OpenAlex

We study the absolute continuity of the convolution $\\delta_{e^X}^\\natural\n\\star \\delta_{e^Y}^\\natural$ of two orbital measures on the symmetric space\n$SO_0(p,q)/SO(p)\\timesSO(q)$, $q>p$. We prove sharp conditions on $X$, $Y\\in\\a$\nfor the existence of the density of the convolution measure. This measure\nintervenes in the product formula for the spherical functions. We show that the\nsharp criterion developed for $\\SO_0(p,q)/\\SO(p)\\times\\SO(q)$ will also serve\nfor the spaces $SU(p,q)/S(U(p)\\timesU(q))$ and $Sp(p,q)/Sp(p)\\timesSp(q)$,\n$q>p$. We also apply our results to the study of absolute continuity of\nconvolution powers of an orbital measure $\\delta_{e^X}^\\natural$.\n

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.
