Deformation cohomology for Yetter-Drinfel'd modules and Hopf (bi)modules

Florin Panaite, Dragos Stefan

If A is a bialgebra over a field k and M, N are either left-right Yetter-Drinfel'd modules or left-right Hopf modules over A, we construct deformation cohomologies H^*(M,N) as tota…

Relating the Connes-Kreimer and Grossman-Larson Hopf algebras built on rooted trees

Florin Panaite

We find a relation between two Hopf algebras built on rooted trees. The first is the Connes-Kreimer Hopf algebra H_R which describes a certain type of renormalization in quantum fi…
