sage: P.<x,y>=IntegerModRing(5)[] sage: f=x*(y^2-x)^2+y^5; sage: g=y^4+y^3-x^2 sage: f.resultant(g) --------------------------------------------------------------------------- TypeError Traceback (most recent call last) .... TypeError: _singular_() got an unexpected keyword argument 'force' That's a bug. (a) the generic _singular_() function doesn't know about force (and shouldn't) (b) IntegerModRing(5) ['x,y'] should be implemented as libsingular polynomials anyway I'll post a patch addressing that issue after the Sphinx-ification (3.3). This works: sage: P.<x,y>=GF(5)[] sage: f=x*(y^2-x)^2+y^5; sage: g=y^4+y^3-x^2 sage: f.resultant(g) -y^11 - y^10 + y^9 sage: factor(_) (-1) * (y - 2)^2 * y^9 Martin -- name: Martin Albrecht _pgp: http://pgp.mit.edu:11371/pks/lookup?op=get&search=0x8EF0DC99 _otr: 47F43D1A 5D68C36F 468BAEBA 640E8856 D7951CCF _www: http://www.informatik.uni-bremen.de/~malb _jab: martinralbre...@jabber.ccc.de --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to sage-devel-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
