Continued Fractions and their Generalizations: A Short History of f-expansions

This book is about the history of f-expansions, their theory, their application, and their connection to other parts of mathematics. Sketches of proofs of some of the theorems about f-expansions---particularly theorems from historical sources---are included not to convince the reader of the truth of the theorem but rather as a way to demonstrate why the theorem is true. These sketches should give a clearer and more easily understood description of the working of the theorem than a hand-waving literary flourish.
