Beschreibung
The main aim of this book is to provide a compact self-contained presentation of the forcing technique devised by Cohen to establish the independence of the continuum hypothesis from the axioms of set theory. The book follows the approach to the forcing technique via Boolean valued semantics independently introduced by Vopenka and Scott/Solovay; it develops out of notes I prepared for several master courses on this and related topics and aims to provide an alternative (and more compact) account of this topic with respect to the available classical textbooks. The aim of the book is to take up a reader with familiarity with logic and set theory at the level of an undergraduate course on both topics (e.g., familiar with most of the content of introductory books on first-order logic and set theory) and bring her/him to page with the use of the forcing method to produce independence (or undecidability results) in mathematics. Familiarity of the reader with general topology would also be quite helpful; however, the book provides a compact account of all the needed results on this matter. Furthermore, the book is organized in such a way that many of its parts can also be read by scholars with almost no familiarity with first-order logic and/or set theory. The book presents the forcing method outlining, in many situations, the intersections of set theory and logic with other mathematical domains. My hope is that this book can be appreciated by scholars in set theory and by readers with a mindset oriented towards areas of mathematics other than logic and a keen interest in the foundations of mathematics.

Unique textbook presenting an accurate and compact account of the topic via boolean valued models Novel point of view outlining connections of forcing with model theory, general topology, functional analysis Novel proofs and account of several fundamental classical results, some of which not covered in the main books

“Writing a book that addresses two distinct audiences is no easy task, and I believe the author has succeeded ... . The book comprises seven chapters over 163 pages, along with five appendices spanning approximately 75 pages. ... I would like to recommend the book to teachers, students, and even professional mathematicians. It serves well both as a textbook and as a valuable reference.” (Rahman Mohammadpour, zbMATH 1565.03003, 2025)
