This volume explains how knot theory and Feynman diagrams can be used to illuminate problems in quantum field theory. The author emphasizes how new discoveries in mathematics have inspired conventional calculational methods for perturbative quantum field theory to become more elegant and potentially more powerful methods. The material.. 5 - The simplest link diagrams; Dirk Kreimer, Johannes Gutenberg Universität Mainz, Germany; Book: Knots and Feynman Diagrams Published online: 04 August 2010. We have seen that the topology of Feynman diagrams relates to knot theory, and Feynman diagrams with a similar topology evaluate to similar numbers. But then, there are relations.
The necessary basics of knot theory are then presented and the number-theoretic relationship between the topology of Feynman diagrams and knot theory is explored. Later chapters discuss four-term relations motivated by the discovery of Vassiliev invariants in knot theory and draw a link to algebraic structures recently observed in..
