| Research Abstract |
One of the aim of this study is to define a homological dimension which corresponds to the ABness of commutative noetherian rings, and to research its properties.
We define an "AB-dimension" which is closely related to the ABness of rings. We show that the "Auslander-Reiten conjecture" is true if the AB-dimension is finite.
