Integrable systems, multicomponent twisted Heisenberg-Virasoro algebra and its central extensions

Abstract

Let {{\displaystyle \mathcal{D}}}_N be the multicomponent twisted Heisenberg-Virasoro algebra. We compute the second continuous cohomology group with coeficients in ℂ and study the bihamiltonian Euler equations associated to {{\displaystyle \mathcal{D}}}_N and its central extensions.

Key words： Bihamiltonian Euler equation; multicomponent twisted Heisenberg-Virasoro algebra
