North Sulawesi babirusa suggestive of a deer's antlers. Together with the other members of the genus "Babyrousa", the North Sulawesi babirusa has usually been considered a subspecies of a widespread "Babyrousa babyrussa", but recent work suggests that there may be several species, differentiable on the basis of geography, body size, amount of body hair, and the shape of the upper canine tooth of the male. Following the split, the "true" "Babyrousa babyrussa" is restricted to Buru and the Sula Islands. Most experts agree that babirusas are part of the pig family, and are one of the oldest living members of the family, representing
Conductor of an abelian variety measure of wild ramification. When "F" is a number field, the conductor ideal of "A" is given by Conductor of an abelian variety In mathematics, in Diophantine geometry, the conductor of an abelian variety defined over a local or global field "F" is a measure of how "bad" the bad reduction at some prime is. It is connected to the ramification in the field generated by the torsion points. For an abelian variety "A" defined over a field "F" as above, with ring of integers "R", consider the Néron model of "A", which is a 'best possible' model of "A"
