Description

Abstract A recent paper (Pakdemirli et al. (2004) [12]) compared three methods of determining approximate symmetries of differential equations. Two of these methods are well known and involve either a perturbation of the classical Lie symmetry generator of the differential system (Baikov, Gazizov and Ibragimov (1988) [7], Ibragimov (1996) [6]) or a perturbation of the dependent variable/s and subsequent determination of the classical Lie point symmetries of the resulting coupled system (Fushchych and ... Title of program: ASP Catalogue Id: AEOG_v1_0 Nature of problem Calculates approximate symmetries for differential equations using any of the three methods as proposed by Baikov, Gazizov and Ibragimov [1,2], Fushchych and Shtelen [3] or Pakdemirli, Yürüsoy and Dolapci [4]. Package includes an altered version of the DESOLVII package (Vu, Jefferson and Carminati [5]). Versions of this program held in the CPC repository in Mendeley Data AEOG_v1_0; ASP; 10.1016/j.cpc.2012.11.012 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018)
