Noncommutative Symmetric Functions Associated with a Code, Lazard Elimination, and Witt Vectors
Jean-Gabriel Luque, Jean-Yves Thibon
Abstract
The construction of the universal ring of Witt vectors is related to Lazard's factorizations of free monoids by means of a noncommutative analogue. This is done by associating to a code a specialization of noncommutative symmetric functions.
