摘要

环的有限小维度被确定为具有有限投影分辨率的模块之间的上投影维度。本文试图证明，对于具有有限弱全维（或戈伦斯坦全维）的相干环，其有限小维等于其弱全维（或戈伦斯坦全维）。因此，我们得出了（戈伦斯坦）冯-诺伊曼环和半遗传环的一些新特征。

The Weak (Gorenstein) Global Dimension of Coherent Rings with Finite Small Finitistic Projective Dimension

The small finitistic dimension of a ring is determined as the supremum projective dimensions among modules with finite projective resolutions. This paper seeks to establish that, for a coherent ring with a finite weak (resp. Gorenstein) global dimension, the small finitistic dimension of is equal to its weak (resp. Gorenstein) global dimension. Consequently, we conclude some new characterizations for (Gorenstein) von Neumann and semihereditary rings.
