Homology 3-Spheres,6] and . Therefore, we can work in all three categories interchangeably. Usually, ℤ-homology spheres are referred to as ., and ℚ-homology spheres as .. Homology 3-spheres exist in abundance. We begin with some examples and constructions.

The Homology Cobordism Group,π;.(.) = 0, only that ..(., ℤ) = 0. A homology sphere . is said to be . if it is homology cobordant to .. or, equivalently, bounds a smooth acyclic 4-manifold. Note that the requirement that the homology cobordism be . is essential — it is known that any integral homology 3-sphere bounds a . compact oriented 4-manifold which is acyclic.
