Quotient Hopf algebras of the free bialgebra with PBW bases and GK-dimensions

Huan Jia, Naihong Hu, Rongchuan Xiong +1

Let $\mathbb{K}$ be a field. We study the free bialgebra $\mathcal{T}$ generated by the coalgebra $C=\mathbb{K}g\oplus \mathbb{K}h$ and its quotient bialgebras (or Hopf algebras…
