<i>λ</i>-Symmetry and <i>μ</i>-Symmetry Reductions and Invariant Solutions of Four Nonlinear Differential Equations

<i>λ</i>-Symmetry and <i>μ</i>-Symmetry Reductions and Invariant Solutions of Four Nonlinear Differential Equations

On one hand, we construct <i>λ</i>-symmetries and their corresponding integrating factors and invariant solutions for two kinds of ordinary differential equations. On the other hand, we present <i>μ</i>-symmetries for a (2+1)-dimensional diffusion equation and derive group-re...
