The renormalization group was originally introduced as a multiscale approach to quantum field theory and the theory of critical phenomena, explaining in particular the universality observed e.g. in critical exponents. Over the years it has become a powerful tool in the mathematical analysis of systems with infinitely many interacting degrees of freedom.

Report on Renormalization Group
2010In this lecture we want to present the problem of the research of automodel probability distributions in comparison with usual integral and local central limit theorems. We think that this approach is instructive for understanding the main mathematical idea underlyng this kind of problems.

Abstract We are part of the way towards understanding the Landau-Ginzburg model in the critical regime. We have been able to calculate two critical exponents, one of which describes the system at T = Tc and the other at T ≠ Tc. If we are prepared to accept the scaling laws for which we found experimental evidence in Chapter 1, and ...

The renormalization group was originally introduced as a multiscale approach to quantum field theory and the theory of critical phenomena, explaining in particular the universality observed e.g. in critical exponents. Since then it has become a hugely important tool in statistical mechanics, condensed matter and high energy physics.
