摘要：
In this paper, we give sharp bounds for the homological dimensions of the Leavitt path algebra L-K(E) of a finite graph E with coefficients in a commutative ring K, as well as establish a formula for calculating the homological dimensions of LK (E) when K is a commutative unital algebra over a field.
