Abstract

fetched live from OpenAlex

Let R be a ring and M a right R -module. M is called ⊕- cofinitely supplemented if every submodule N of M with M / N finitely generated has a supplement that is a direct summand of M . In this paper various properties of the ⊕-cofinitely supplemented modules are given. It is shown that (1) Arbitrary direct sum of ⊕-cofinitely supplemented modules is ⊕-cofinitely supplemented. (2) A ring R is semiperfect if and only if every free R -module is ⊕-cofinitely supplemented. In addition, if M has the summand sum property, then M is ⊕-cofinitely supplemented iff every maximal submodule has a supplement that is a direct summand of M .

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.
