Abstract
The notion of commutative integrodifferential algebra was introduced for the algebraic study of boundary problems for linear ordinary differential equations. Its noncommutative analog achieves a similar purpose for linear systems of such equations. In both cases, free objects are crucial for analyzing the underlying algebraic structures, e.g. of the (matrix) functions. In this paper we apply the method of GroebnerShirshov bases to construct the free (noncommutative) integrodifferential algebra on a set. The construction is from the free RotaBaxter algebra on the free differential algebra on the set modulo the differential RotaBaxter ideal generated by the noncommutative integration by parts formula. In order to obtain a canonical basis for this quotient, we first reduce to the case when the set is finite. Then in order to obtain the monomial order needed for the CompositionDiamond Lemma, we consider the free RotaBaxter algebra on the truncated free differential algebra. A CompositionDiamond Lemma is proved in this context, and a GroebnerShirshov basis is found for the corresponding differential RotaBaxter ideal.
