Her hope is that this decision will leave the definition of a " woman 's health " ambiguous so that it can be used to expand the circumstances in which a woman can get an abortion in the future . Others wished to change the received definition of a lie . For example , the definition of a Unit-of-Measure was circular . Given a zero-dimensional ideal I of a polynomial ring over a field with lexicographical order , return a triangular decomposition of I as a sequence Q of ideals such that the intersection of the ideals of Q equals I and for each ideal J of Q which is radical , J is triangular ( see above for the definition of a triangular ideal ) . Or possibly , I might check the definition of a subject term , and then go back to the subject catalogue .
