| 11:00 - 13:00 Commutative Algebra Webinar Cohen-Macauly Homological Dimensions School MATHEMATICS 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. https://zoom.us/join Meeting ID: 908 611 6889 Passcode: 362880 ... |
