Oriented Four Dimensional Orbifolds and their Cobordism
by

In contrast to two and three dimensional oriented orbifolds, which all bound, there are many oriented four orbifolds which cannot bound any oriented orbifold. We determine what the singular sets in four dimensional orbifolds can look like and then which of these orbifolds can bound. We give a complete description of the group of cobordism classes of oriented four orbifolds.
