Appendix A: Extension to Euclidean Models and point out where in the literature these extensions can be found in full detail. Although the renormalisation group philosophy remains the same for the hierarchical and Euclidean models, the Euclidean setting requires significant adjustments. These include: an extended version of the perturbativ

Book 2019ation group. Lastly it discusses the relation of these topics to the self-avoiding walk and supersymmetry...Including exercises in each chapter to help readers deepen their understanding, it is a valuable resource for mathematicians and mathematical physicists wanting to learn renormalisation group theory..

Spin Systemsin a self-contained manner. The Gaussian free field is introduced and its relation to simple random walk is explained. The notion of universality is discussed. Recent results for the critical behaviour of the |.|. model are summarised, including the existence of logarithmic corrections to mean-field critical exponents in dimension . = 4.

Flow Equations and Main Resultt be ignored, and we state the extension of the results for the perturbative flow to its nonperturbative version and use this extension to prove the main results for the |.|. model. The analysis of the nonperturbative effects is carried out in subsequent chapters. The notion of infrared asymptotic freedom is discussed.

The Hierarchical Model proved in this book, which gives the critical behaviour of the susceptibility of the 4-dimensional hierarchical |.|. model. In preparation for the proof of the main result, we reformulate the hierarchical |.|. model as a perturbation of a Gaussian integral.
