摘要: We introduce and investigate a new injective version of the complete intersection dimension Avramov, Gasharov, Peeva. It is like Sahandi, Sharif, Yassemi in that it built using quasi-deformations. Ours different, however, we use Hom functor place tensor product. show (a) this invariant characterizes property for local rings, (b) fits between classical G-injective Enochs Jenda, (c) provides modules with Bass numbers are bounded by polynomials, (d) improves theorem Peskine, Szpiro, Roberts (Bass’ conjecture).
