abstract: | This paper discusses various deformations of free associative algebras and of their convolution algebras. Our main
examples are deformations of noncommutative symmetric functions related to
families of idempotents in descent algebras, and a simple q-analogue of the
shuffle product, which has unexpected connections with quantum groups, hyperplane
arrangements, and certain questions in mathematical physics (the quon algebra,
generalized Brownian motion).
