摘要
We consider a Lie algebra generalizing the Virasoro algebra to the case of two space variables. We study its coadjoint representation and calculate the corresponding Euler equations. In particular, we obtain a bi- Hamiltonian system that leads to an integrable non- linear partial differential equation. This equation is an analogue of the Kadomtsev - Petviashvili ( of type B) equation.
