abstract = { We propose a differential analog of the notion of integral closure of
algebraic function fields. We present an algorithm for computing the
integral
closure of the algebra defined by a linear differential operator. Our
algorithm
is a direct analog of van Hoeij's algorithm for computing integral bases of
algebraic function fields.},
