## Knots, Groups, and 3-manifolds: Papers Dedicated to the Memory of R. H. FoxRalph Hartzler Fox, Lee Paul Neuwirth There is a sympathy of ideas among the fields of knot theory, infinite discrete group theory, and the topology of 3-manifolds. This book contains fifteen papers in which new results are proved in all three of these fields. These papers are dedicated to the memory of Ralph H. Fox, one of the world's leading topologists, by colleagues, former students, and friends. |
