Conservation laws, symmetry reductions, and exact solutions of some Keller–Segel models

open access: yesAdvances in Difference Equations, 2018
In this paper, three Keller–Segel models are considered from the point of Lie symmetry analysis, conservation laws, symmetry reduction, and exact solutions. By means of Lie symmetry analysis, we first obtain all the symmetries for the three models. Based

Conservation laws for perturbed solitons in optical metamaterials

open access: yesResults in Physics, 2018
The conservation laws for the dynamics of soliton propagation through optical metamaterials are derived by the aid of Lie symmetry analysis. The proposed model will be studied with two forms of nonlinearity. They are Kerr law and parabolic law. Keywords:
