8. Equivalent Lagrangian and Lie Symmetry Analysis of a Class of Kuramoto Sivashinsky(KS)Equations by J. E. Okeke and M. Laisin Transactions of NAMP Vol. 5,(Sept and Nov., 2017), pp 61 – 64
Sale price: $5.00
The equivalent Lagrangians of a class of Kuramoto Sivashinky equations are constructed via Noether approach. A remarkable feature of these Lagrangians, constructed through point transformations of the symmetries, is that they preserve the symmetry structures of the original Lagrangians
