典范模的嵌入与连通和的分解
Embeddings of canonical modules and resolutions of connected sums
摘要:
对于一个理想的$I_{m,n}$,我们得到了$m$的一个典范模到$R/I_{m,n}$自身的一个特殊嵌入.这种显式嵌入的构造依赖于由$I_{m,n}$生成的理想的最小自由$R$ -分辨率。利用这种嵌入,我们给出了某些Artinian $k$ -代数(其中$k$是域)的多个副本的连通和的分解.
英文摘要:
For an ideal $I_{m,n}$ generated by all square-free monomials of degree $m$ in a polynomial ring $R$ with $n$ variables, we obtain a specific embedding of a canonical module of $R/I_{m,n}$ to $R/I_{m,n}$ itself. The construction of this explicit embedding depends on a minimal free $R$-resolution of an ideal generated by $I_{m,n}$. Using this embedding, we give a resolution of connected sums of several copies of certain Artinian $k$-algebras where $k$ is a field.
