On symmetric powers of differential operators

We present alternative algorithms for computing symmetric powers of linear ordinary differential operators. Our algorithms are applicable to operators with coefficients in arbitrary integral domains and become faster than the traditional methods for symmetric powers of sufficiently large order, or over sufficiently complicated coefficient domains. The basic ideaa are also applicable to other computations involving cyclic vector techniques, such as exterior powers of differential or difference operators.
