Approximate and Renormgroup Symmetries

• Lie Group Analysis in Outline.- Approximate Transformation Groups and Symmetries.- Symmetries of Integro-Differential Equations.- Renormgroup Symmetries.- Applications of Renormgroup Symmetries.

From the reviews: "The book is dedicated to new trends in applied group analysis focused on the computation of approximate symmetries of differential equation systems containing a small parameter. ... Many worked out examples are offered illustrating the general theory. ... This is a short, self contained book providing a valuable reference for the application-oriented reader."
