We present liftings of Nichols algebras of type B3 in finite-dimensional pointed Hopf algebras, indicating significant algebraic structures.
We give an explicit presentation of a family of finite-dimensional pointed Hopf algebras over an algebraically closed field of characteristic zero that constitute all liftings of Nichols algebras of diagonal Cartan type B3 over a finite abelian group.
