%0 Journal Article %T Global Gorenstein dimensions %A Driss Bennis %A Najib Mahdou %J Mathematics %D 2006 %I arXiv %X In this paper, we prove that the global Gorenstein projective dimension of a ring $R$ is equal to the global Gorenstein injective dimension of $R$, and that the global Gorenstein flat dimension of $R$ is smaller than the common value of the terms of this equality. %U http://arxiv.org/abs/math/0611358v4
