同调维数与正则环

Homological dimensions and regular rings

Alina Iacob, Srikanth B. Iyengar

摘要:

Avramov和Foxby关于复形的内射维数的一个问题在诺特环类中得到了肯定的解决。证明中的一个关键步骤是将现有问题转化为关于内射模复形的同伦范畴的问题。对平坦维数和投射维数也建立了类似的结果。

英文摘要:

A question of Avramov and Foxby concerning injective dimension of complexes is settled in the affirmative for the class of noetherian rings. A key step in the proof is to recast the problem on hand into one about the homotopy category of complexes of injective modules. Analogous results for flat dimension and projective dimension are also established.
