Abstract

We solve the group classification problem for the 2+12+1 generalized quantum Zakharov-Kuznetsov equation. Particularly we consider the generalized equation ut+f(u)uz+uzzz+uxxz=0u_{t}+f\left( u\right) u_{z}+u_{zzz}+u_{xxz}=0, and the time-dependent Zakharov-Kuznetsov equation ut+δ(t)uuz+λ(t)uzzz+ε(t)uxxz=0u_{t}+\delta \left( t\right) uu_{z}+\lambda \left( t\right) u_{zzz}+\varepsilon \left( t\right) u_{xxz}=0% . Function f(u)f\left( u\right) and δ(t), λ(t)\delta \left( t\right) ,~\lambda \left( t\right) ,~ε(t)\varepsilon \left( t\right) are determine in order the equations to admit additional Lie symmetries.\ Finally, we apply the Lie invariants to find similarity solutions for the generalized quantum Zakharov-Kuznetsov equation.
