Abstract

In this paper, the notions of quasi-triangular and factorizable dual pre-Poisson bialgebras are introduced. A factorizable dual pre-Poisson bialgebra induces a factorization of the underlying dual pre-Poisson algebra, and the double of any dual pre-Poisson bialgebra is factorizable. We introduce the notion of quadratic Rota-Baxter dual pre-Poisson algebras and show that there is a one-to-one correspondence between factorizable dual pre-Poisson bialgebras and quadratic Rota-Baxter Poisson algebras of nonzero weights. Moreover, a method of constructing infinite-dimensional dual pre-Poisson bialgebras using finite-dimensional Poisson bialgebras is given. We prove that there is a completed dual pre-Poisson bialgebra structure the tensor product of a Poisson bialgebra and a quadratic $\bz$-graded perm algebra, and this completed dual pre-Poisson bialgebra structure is coboundary (resp. quasi-triangular, triangular) if the original Poisson bialgebra is coboundary (resp. quasi-triangular, triangular). The induced factorizable finite-dimensional dual pre-Poisson bialgebras are considered.
