$p^3$阶Heisenberg群的群行列式

The Integer group determinants for the Heisenberg group of order $p^3$

Michael J. Mossinghoff, Christopher Pinner

摘要:

建立了$p^3$阶非交换Heisenberg群的整群行列式所满足的一个同余.我们刻画了所有行列式值与$p$互质,给出了$p$的倍数的可整除性条件,并确定了当$p=3$ .我们还为$\mathbb Z_p^2$的$p$划分群行列式的幂提供了新的尖锐条件.对于有限群,整群行列式可以理解为对应于Lind推广的Mahler测度。我们推测的Lind-Mahler措施的离散海森堡群和其他两个无限的非阿贝尔群所产生的对称性的平面和3-空间。

英文摘要:

We establish a congruence satisfied by the integer group determinants for the non-abelian Heisenberg group of order $p^3$. We characterize all determinant values coprime to $p$, give sharp divisibility conditions for multiples of $p$, and determine all values when $p=3$. We also provide new sharp conditions on the power of $p$ dividing the group determinants for $\mathbb Z_p^2$. For a finite group, the integer group determinants can be understood as corresponding to Lind's generalization of the Mahler measure. We speculate on the Lind-Mahler measure for the discrete Heisenberg group and for two other infinite non-abelian groups arising from symmetries of the plane and 3-space.
