Deformation by cocycles of pointed Hopf algebras over non-abelian groups
We explore a method for explicitly constructing multiplicative 2-cocycles for bosonizations of Nichols algebras B(V ) over Hopf algebras H. These cocycles arise as liftings of H-invariant linear functionals on V⊗ V and give a formula for deforming braidedcommutator- Type relations. Using this constr...

| Sumario: | We explore a method for explicitly constructing multiplicative 2-cocycles for bosonizations of Nichols algebras B(V ) over Hopf algebras H. These cocycles arise as liftings of H-invariant linear functionals on V⊗ V and give a formula for deforming braidedcommutator- Type relations. Using this construction, we show that all known finite-dimensional pointed Hopf algebras over the dihedral groups Dm with m = 4t≥12, over the symmetric group S3, and some families over S4 are cocycle deformations of bosonizations of Nichols algebras. |
