Abstract

fetched live from OpenAlex

Abstract We study Tychonoff spaces X with the property that, for all topological embeddings X → Y , the induced map C ( Y ) → C ( X ) is an epimorphism of rings. Such spaces are called absolute 𝒞ℛ-epic. The simplest examples of absolute 𝒞ℛ-epic spaces are σ -compact locally compact spaces and Lindelöf P -spaces. We show that absolute CR -epic first countable spaces must be locally compact. However, a “bad” class of absolute CR -epic spaces is exhibited whose pathology settles, in the negative, a number of open questions. Spaces which are not absolute CR -epic abound, and some are presented.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
