Group and Renormgroup Symmetry of Quasi-Chaplygin Media
Tóm tắt
Results of renormgroup analysis of a quasi-Chaplygin system of equations are presented. Lie-Bäcklund symmetries and corresponding invariant solutions for different “Chaplygin” functions are obtained. The algorithm of construction of a group on a solution (renormgroup) using two different approaches is discussed.
