Abstract

In this paper we consider the Poisson algebraic structure associated with a classical rr-matrix, i.e. with a solution of the modified classical Yang--Baxter equation. In Section 1 we recall the concept and basic facts of the rr-matrix type Poisson orbits. Then we describe the rr-matrix Poisson pencil (i.e the pair of compatible Poisson structures) of rank 1 or CPnCP^n-type orbits of SL(n,C)SL(n,C). Here we calculate symplectic leaves and the integrable foliation associated with the pencil. We also describe the algebra of functions on CPnCP^n-type orbits. In Section 2 we calculate the Poisson homology of Drinfeld--Sklyanin Poisson brackets which belong to the rr-matrix Poisson family.
