Let R be a Noetherian local ring and Ω an arbitraryR-module of finite depth and finite projective dimension. The flat dimension of Ω is at leastdepth(R)−depth(Ω) with equality in the following cases: (i) Ω is finitely generated over some Noetherian local R-algebraS; (ii) dim(R) = 1; (iii) dim(R) = 2 andΩ is separated; (iv) R is CohenMacaulay,dim(R) = 3 andΩ is complete.
