整格的新不变量
New invariants for integral lattices
摘要:
设$Λ$是欧几里得空间中的任意整格。已经证明,对于每一个整数$n>0$,有一个超球面正好通过$Λ$的$n$点。利用这一结果,我们引入了新的格不变量,并给出了与类数为1的二维欧氏格有关的一些计算结果。
英文摘要:
Let $Λ$ be any integral lattice in Euclidean space. It has been shown that for every integer $n>0$, there is a hypersphere that passes through exactly $n$ points of $Λ$. Using this result, we introduce new lattice invariants and give some computational results related to two-dimensional Euclidean lattices of class number one.
