We introduce the Hopf algebra of quasi-symmetric func-tions with semigroup exponents generalizing the Hopf alge-bra QSymof quasi-symmetric functions. As a special case we obtain the Hopf algebra QSym_N of weak quasi-symmetric functions, which provides a framework for the study of a ques-tion proposed by G.-C.Rota relating symmetric type func-tions and Rota–Baxter algebras. We provide the transforma-tion formulas between the weak monomial and fundamental quasi-symmetric functions, which extends the corresponding results for quasi-symmetric functions. Moreover, we show that QSym is a Hopf subalgebra and a Hopf quotient algebra of QSym_N. Rota’s question is addressed by identifying QSym_N with the free commutative unitary Rota–Baxter algebra \sha(x)of weight 1 on one generator x, which also allows us to equip \sha(x) with a Hopf algebra structure.
