 Post subject: About the number of generators of an ideal - II
PostPosted: Thu Aug 11, 2005 5:32 pm 
In my last mail I forgot to mention this...

I am also interested in finding the quotient of two ideals.
i.e.
R: ring, I,J subset R be the ideals in R. Then I want to
find the ideal I:J.

So I want to know the algorithm/theory used to find out the
generators of I:J.

Thanks in advance

In SINGULAR, you can find it with the help of command "quotient", see
http://www.singular.uni-kl.de/Manual/2-0-5/sing_261.htm

Theoretical issues could be found, for example, in the SINGULAR book, p.79-80, subsection 1.8.8.

Alternatively, there is a short description of the algorithm in the paper of Hans Schoenemann "Algorithms in SINGULAR".
The HTML version of the article is available at

With best regards,
