Hello all, I define an ideal "jed" in the ring R=(0,a,b,c,d),(x,y,z,u,v),dp I compute ideal gb=groebner(jed) and save it in a file. I start another session and read "gb". When I try to use it to reduce a poly mod gb, I get the message // ** gb is no standard basis What is wrong? Thanks in advance for any explanation. DZ Djokovic |

This warning appears for all generating sets which are used where a groebner basis is required, but which are not a result of groebner/std/fglm. This applyes also to your case: jed is (in the second run) a result of a read statement. If you are sure that your generating set is indeed a groebner basis, you may set the corresponding attribute: attrib(jed,"isSB",1); |
