By Jonathan Hillman

This booklet serves as a reference on hyperlinks and at the invariants derived through algebraic topology from masking areas of hyperlink exteriors. It emphasizes the positive factors of the multicomponent case now not typically thought of through knot-theorists, corresponding to longitudes, the homological complexity of many-variable Laurent polynomial earrings, the truth that hyperlinks usually are not frequently boundary hyperlinks, unfastened coverings of homology boundary hyperlinks, the reduce relevant sequence as a resource of invariants, nilpotent finishing touch and algebraic closure of the hyperlink staff, and disc hyperlinks. Invariants of the kinds thought of right here play an important position in lots of functions of knot idea to different components of topology.

This moment version introduces new chapters -- twisted polynomial invariants and singularities of aircraft curves. each one replaces short sketches within the first version. bankruptcy 2 has been reorganized, and new fabric has been extra to 4 different chapters.
