# Quotient of ideals in powerseries ring

Is it possible to take quotient (colon) of two ideals in a multivariable powerseries ring over a field?

e.g. the following code gives me error(s):

sage: R.<x,y,z> = PolynomialRing(QQ,3)
sage: I = Ideal([x^2+x*y*z,y^2-z^3*y,z^3+y^5*x*z])
sage: J = Ideal([x])
sage: Q = I.quotient(J)


Thanks and regards

The code you posted gives me no errors (in version 4.7.1). Did you mean to make R a power series ring? If you did, that would certainly give you errors as ideal quotients have not been implemented for power series rings.

I precisely mean to take R as a Power Series Ring. Is it that the same algorithm (as that for Polynomials) does not work for Power Series? In that case where is the problem?

The problem is that no one has implemented the algorithm! If you're interested, you should do it :)
