PrincipalIdealDomain¶
catdef.spad line 1300 [edit on github]
The category of constructive principal ideal domains, i.e. where a single generator can be constructively found for any ideal given by a finite set of generators. Note that this constructive definition only implies that finitely generated ideals are principal. It is not clear what we would mean by an infinitely generated ideal.
