Mathematical Aspects
In this section we consider some fundamental mathematical questions that arise as soon as one want to manipulate mathematical expressions in a computer. We consider mainly the case of the multivariate rational fractions. This is not a real restriction, because, as soon as the irrational functions appearing in an expression are simplified, they are usually considered as new indeterminates. For example is viewed as a polynomial in and
