The Hopf algebras of type B quasisymmetric functions and peak functions

The Hopf algebras of type B quasisymmetric functions and peak functions

We show that with the appropriate choice of coproduct, the type B quasisymmetric functions form a Hopf algebra, and the recently introduced type B peak functions form a Hopf subalgebra.
