Download or read book 2-Knots and Their Groups written by Jonathan Hillman and published by CUP Archive. This book was released on 1989-03-30 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: To attack certain problems in 4-dimensional knot theory the author draws on a variety of techniques, focusing on knots in S^T4, whose fundamental groups contain abelian normal subgroups. Their class contains the most geometrically appealing and best understood examples. Moreover, it is possible to apply work in algebraic methods to these problems. Work in four-dimensional topology is applied in later chapters to the problem of classifying 2-knots.
