In mathematics, the ith Bass number of a module M over a local ring R with residue field k is the k-dimension of Ext R i . More generally the Bass number μ i of a module M over a ring R at a prime ideal p is the Bass number of the localization of M for the localization of R. Bass numbers were introduced by Hyman Bass (1963, p.11). The Bass numbers describe the minimal injective resolution of a finitely-generated module M over a Noetherian ring: for each prime ideal p there is a corresponding i
