Abstract

fetched live from OpenAlex

Abstract Operator Theory by Example is aimed at graduate students just getting started in operator theory. Rather than discuss the subject in the abstract, this book covers the subject through twenty instructive examples of a wide variety of operators. For each operator, we discuss its norm, spectrum, commutant, invariant subspaces, and interesting properties that are particular to that operator. An important feature of this book is dozens of exercises at the end of each chapter (over 600 in total) along with hints. These problems are designed to give the reader an opportunity to master the topics covered in the chapter as well as give them an opportunity to further explore the vast operator theory literature. Each chapter also contains well researched historical facts which place the chapter in context so the reader can see the development of the field.

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.
