Subresultants of two Hermite–Laurent series

Subresultants appear to be approximants of the resultant, and can be defined, in the univariate case so far, for a couple of Laurent series while the concept of resultant does no longer make sense. Extending the definition of Hermite polynomials to Laurent series we compute the subresultants of two...

Summary:Subresultants appear to be approximants of the resultant, and can be defined, in the univariate case so far, for a couple of Laurent series while the concept of resultant does no longer make sense. Extending the definition of Hermite polynomials to Laurent series we compute the subresultants of two Hermite–Laurent series.
