Approximate groups and renormgroup symmetries
Blekinge Institute of Technology, School of Engineering, Department of Mathematics and Natural Sciences2008 (English)Book (Other academic)
The book deals with so-called renormalization group symmetries considered in the framework of approximate transformation groups. Renormgroup symmetries provide a basis for the renormgroup algorithm for improving solutions to boundary value problems by converting "less applicable solutions" into "more applicable solutions". the algorithm is particularly useful for improving approximate solutions given by the perturbation theory.
