论文摘要
在本文中,我们将证明,如果$ d $是足够大的无平方的正理性整数,那么超过$ \ mathcal {o} _f $的积分septenary septenary septenary septenary通用二次晶格,其中$ f = \ mathbb q(\ sqrt {d})$。
In this paper, we will prove that if $d$ is sufficiently large square-free positive rational integer, then there is no integral septenary universal quadratic lattice over $\mathcal{O}_F$ where $F=\mathbb Q(\sqrt{d})$.
