Over the last fifteen years the face of knot theory has changed due to various new theories and invariants coming from physics topology combinatorics and alge-bra. It suffices to mention the great progress in knot homology theory (Khovanov homology and Ozsvath-Szabo Heegaard-Floer homology) the A-polynomial which give rise to strong invariants of knots and 3-manifolds in particular many new unknot detectors. New to this Edition is a discussion of Heegaard-Floer homology theory and A-polynomial of classical links as well as updates throughout the text. Knot Theory Second Edition is notable not only for its expert presentation of knot theoryâs state of the art but also for its accessibility. It is valuable as a profes-sional reference and will serve equally well as a text for a course on knot theory. . Language: English
