Abstract

fetched live from OpenAlex

Алгебра симметрий вещественного эллиптического уравнения Лиувилля является бесконечномерной алгеброй с простой алгеброй Ли $o(3,1)$ в качестве максимальной подалгебры. Полная алгебра порождает конформную группу евклидовой плоскости $E_2$. Наличие такой бесконечномерной алгебры отличает эллиптическое уравнение Лиувилля от гиперболического, алгебра симметрий которого представляет собой прямую сумму двух алгебр Вирасоро. С использованием ранее предложенной процедуры дискретизации представлена разностная схема, инвариантная относительно группы $O(3,1)$ и в непрерывном пределе переходящая в эллиптическое уравнение Лиувилля. Дискретная решетка является решением $O(3,1)$-инвариантного уравнения и сама инвариантна относительно некоторой подгруппы группы $O(3,1)$, а именно группы $O(2)$ поворотов евклидовой плоскости.

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.
