Infinite-dimensional pre-Lie bialgebras induced from Leibniz-dendriform bialgebras and Zinbiel-dendriform bialgebras

In this paper, we establish a completed pre-Lie bialgebra structure on the tensor product of a Leibniz-dendriform bialgebra and a quadratic $\mathbb{Z}$-graded Zinbiel algebra.

We also obtain such a structure on the tensor product of a Zinbiel-dendriform bialgebra and a quadratic $\mathbb{Z}$-graded Leibniz algebra.

Moreover, a Zinbiel-dendriform bialgebra is precisely one whose affinization by a special quadratic $\mathbb{Z}$-graded Leibniz algebra is a completed pre-Lie bialgebra.

Finally, using solutions of the ZD-YBE (resp.~LD-YBE) with invariant skew-symmetric parts in a Zinbiel-dendriform (resp.~ Leibniz-dendriform) algebra, we construct completed solutions possessing invariant symmetric parts of the $S$-equation in the induced pre-Lie algebra.
