Witt and Virasoro algebras as Lie bialgebras
An infinite family of solutions of the classical Yang-Baxter equation in the Witt and Virasoro Lie algebras is presented. It is shown that the corresponding triangular Lie bialgebra structures are not isomorphic, in char 0. The relation of the dual structures with linearly recursive sequences is discussed.
