On realizations of the Virasoro algebra
Renat Zhdanov, Qing Huang
We obtain complete classification of in-equivalent realizations of the Virasoro algebra by Lie vector fields over the three-dimensional field of real numbers. As an application we…

On contact symmetries of evolution equations
Qing Huang, Renat Zhdanov, Changzheng Qu
In this paper, we develop an algebraic approach to classifying contact symmetries of the second-order nonlinear evolution equations. Up to contact isomorphisms, all inequivalent PD…
