Abstract: |
In this paper, the finitistic flat dimension FFD(R) of rings is studied. By using homological transformation, the homological calculation method of FFD(R) is obtained. Thus, the change theorem of rings of FFFD(R) and the calculation method of this dimension over coherent rings are given. |
