我们提供了无限域上不定数对称矩阵的行列式环的几乎 Gorenstein 性质的表征。我们使用 Schur 函子给出了行列式环解析中最后两个模块的等级的显式公式。
We provide a characterization of the almost Gorenstein property of determinantal rings of a symmetric matrix of indeterminates over an infinite field. We give an explicit formula for ranks of the last two modules in the resolution of determinantal rings using Schur functors.
