Abstract

Abstract With the aim of to pologizing domains of matrices with natural topologies, we mainly study FK-spaces in this chapter. These are sequence spaces carrying a metrizable locally convex topology which is complete (F-space) such that convergence implies coordinatewise convergence (K-space). FK-space theory was initiated by K. Zeller in 1949. On the one hand it makes possible the application of functional analytic methods to a number of major problems in summability and, on the other hand, it has proved very fruitful in the development of some topics in functional analysis, for example that of topological sequence spaces. Definitely, the inspiration for FK-space theory came from the Polish school around S. Banach, S. Mazur and W. Orlicz in which functional analytic methods were applied, for instance, to prove the bounded consistency theorem. Around 1949, K. Zeller published some seminal papers, for example, [261], [260], [262]. The subject was then further developed by Zeller and many other mathematicians. Wilansky’s book, [254], traces the development of the subject up to 1984.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
