论文摘要
我们研究了与D(2)类型$ G(P,P,P-1)$的问题有关的问题,其中$ p $是一个奇怪的素数。具体而言,我们以纳迪姆的论文为基础\ cite {jamil},这表明$ \ mathbb {z} [g(5,4)] $ - module $ \ mathbb {z} $允许对斜分辨率和第三个syzygy $ω_3(z______________} $ \ z} $ c {z} $ { $ r(2)\ oplus [y-1)$。在此结果的激励下,我们证明了$ \ mathbb {z} [g(p,p,p-1)] $ - 模块$ r(2)\ oplus [y-1)$对于任何奇数prime $ p $既饱满,又是直的。 Given Johnson's work on the D(2)-Problem \cite{D2}, this leads to the conclusion that $G(5,4)$ satisfies the D(2)-property, as well as providing a sufficient condition for the D(2)-property to hold for $G(p,p-1)$, namely the condition that $R(2)\oplus[y-1)$ is a minimal representative for $ \ mathbb {z} [g(p,p,p-1)] $上的$ω_3(\ mathbb {z})$,我们称为条件m(p)。遵循此结果,我们证明了一个定理,该定理简化了证明条件M(p)所需的计算。最后,在$ p = 7 $并证明M(7)持有的情况下,我们进行了这些计算,这足以证明$ g(7,6)$满足D(2) - 专业。
We study problems relating to the D(2)-Problem for metacyclic groups of type $G(p,p-1)$ where $p$ is an odd prime. Specifically we build on Nadim's thesis \cite{Jamil}, which showed that the $\mathbb{Z}[G(5,4)]$-module $\mathbb{Z}$ admits a diagonal resolution and a minimal representative for the third syzygy $Ω_3(\mathbb{Z})$ is $R(2)\oplus[y-1)$. Motivated by this result, we show that the $\mathbb{Z}[G(p,p-1)]$-module $R(2)\oplus[y-1)$ is both full and straight for any odd prime $p$. Given Johnson's work on the D(2)-Problem \cite{D2}, this leads to the conclusion that $G(5,4)$ satisfies the D(2)-property, as well as providing a sufficient condition for the D(2)-property to hold for $G(p,p-1)$, namely the condition that $R(2)\oplus[y-1)$ is a minimal representative for $Ω_3(\mathbb{Z})$ over $\mathbb{Z}[G(p,p-1)]$, which we refer to as the condition M(p). Following this result, we prove a theorem which simplifies the calculations required to show that the condition M(p) holds. Finally, we carry out these calculations in the case where $p=7$ and prove that the condition M(7) holds, which is sufficient to show that $G(7,6)$ satisfies the D(2)-property.
