摘要: A new homological invariant is introduced for a finite module over commutative noetherian ring: its CI-dimension. In the local case, sharp quantitative and structural data are obtained modules of CI-dimension, providing first class (possibly) infinite projective dimension with rich structure theory free resolutions.
