关于参数化toric码

On parameterised toric codes

Esma Baran, Mesut Şahin

摘要:

设$X$是有限域上具有分裂环面$T_X$的完全单纯环面簇.对于任何矩阵$Q$,我们感兴趣的是由$Q$的列参数化的$T_X$的子群$Y_Q$。我们给出了一个算法来获得唯一格$L$的基础,其格理想$I_L$是$I(Y_Q)$。给出了计算$Y_Q$的阶数的两种直接算法,即计算相应码${\cC}_{å,Y_Q}$的长度。我们在\verb |Macaulay2|中共享实现它们的程序。最后,利用子群$Y_Q$的参数描述,给出了${\cC}_{å,Y_Q}$的最小距离的下界。作为应用,我们计算了Hirzebruch曲面$\cl H_{\ell}$上复曲面码的主要参数,推广了Hansen的相应结果.

英文摘要:

Let $X$ be a complete simplicial toric variety over a finite field with a split torus $T_X$. For any matrix $Q$, we are interested in the subgroup $Y_Q$ of $T_X$ parameterized by the columns of $Q$. We give an algorithm for obtaining a basis for the unique lattice $L$ whose lattice ideal $I_L$ is $I(Y_Q)$. We also give two direct algorithmic methods to compute the order of $Y_Q$, which is the length of the corresponding code ${\cC}_{å,Y_Q}$. We share procedures implementing them in \verb|Macaulay2|. Finally, we give a lower bound for the minimum distance of ${\cC}_{å,Y_Q}$, taking advantage of the parametric description of the subgroup $Y_Q$. As an application, we compute the main parameters of the toric codes on Hirzebruch surfaces $\cl H_{\ell}$ generalizing the corresponding result given by Hansen.
