Abstract: We introduce the Hopf algebra of quasi-symmetric functions with semigroup exponents generalizing the Hopf algebra QSym of quasi-symmetric functions. As a special case we obtain the Hopf algebra WCQSym of weak composition quasi-symmetric functions, which provides a framework for the study of a question proposed by G.-C. Rota relating symmetric type functions and Rota-Baxter algebras. We show that QSym is a Hopf subalgebra and a Hopf quotient algebra of WCQSym. Rota’s question is addressed by identifying WCQSym with the free commutative unitary Rota-Baxter algebra of weight 1 on one generator. Extending the close relationship between
quasi-symmetric functions and multiple zeta values, weighted multiple zeta values and a q-analog of multiple zeta values are investigated, and a decomposition formula is established.
