SUMMARY |
|
| |
We introduce new homological dimensions, namely the Cohen-Macaulay
projective, injective and flat dimensions for homologically bounded complexes.
Among other things we show that (a) these invariants characterize the CohenMacaulay property for local rings, (b) Cohen-Macaulay flat dimension fits between the Gorenstein flat dimension and the large restricted flat dimension, and
(c) Cohen-Macaulay injective dimension fits between the Gorenstein injective dimension and the Chouinard invariant.
