嵌入余深度为3的局部环。示例

Local rings of embedding codepth 3. Examples

Lars Winther Christensen, Oana Veliche

摘要:

嵌入余深度为3的完全局部环在正则局部环上有长度为3的最小自由分解.这样的决议进行微分分次代数结构,基于此可以分类嵌入余深度3的局部环。我们给出的例子代数结构已被证明不会发生。

英文摘要:

A complete local ring of embedding codepth 3 has a minimal free resolution of length 3 over a regular local ring. Such resolutions carry a differential graded algebra structure, based on which one can classify local rings of embedding codepth 3. We give examples of algebra structures that have been conjectured not to occur.
