Whle doing a program, i found a problem when trying to compute the syzygy module of an ideal of polynomials over the complexes.
Here is the code tha showed the error: R.<x,y,z>=PolynomialRing(CC) config2=(x^2+8*y^2+21*x*y-x*z-8*y*z)*(x^2+5*y^2+13*x*y- x*z-5*y*z)*(x^2+9*y^2-4*x*y-x*z-9*y*z)*(x^2+11*y^2+x*y- x*z-11*y*z)*(x^2+17*y^2-5*x*y-x*z-17*y*z) miid=R.ideal(diff(config2,x),diff(config2,y),diff(config2,z),config2) miid.syzygy_module() *** this shows the error By trying to send the ideal to singular and calculate the syzygys there "by hand", i also found an error when i typed: singular.ideal(miid) When i defined different rings, it did work OK.
