Hi everybody, in a nutshell I want to compute something like this MAGMA session in Sage:
%magma P<a,b,c,d> := PolynomialRing(GF(127),4); I := ideal<P|c^3-b*d^2,b*c-a*d,b^3-a^2*c,a*c^2-b^2*d>; S<t> := HilbertSeries(I); S; L<u> := LaurentSeriesRing(IntegerRing()); L ! S; The first part is quite easy as I wrapped the appropriate Singular function (singular.hilb(I,1)/(1-t^n)). It is the second part that gives me trouble, i.e. I need the first n Laurent series terms for the rational function which describes the Hilbert series. Tips?
