关于极大序模格的一个Mordell不等式
A Mordell Inequality for Lattices over Maximal Orders
摘要:
本文证明了有限维复或四元数Hermitian空间中的格是虚二次数域或全定有理四元数代数中极大序模上的模时的Mordell不等式的一个类似结果。这个不等式意味着16维Barnes-Wall格在所有具有Hurwitz结构的16维格中具有最优密度。
英文摘要:
In this paper we prove an analogue of Mordell's inequality for lattices in finite-dimensional complex or quaternionic Hermitian space that are modules over a maximal order in an imaginary quadratic number field or a totally definite rational quaternion algebra. This inequality implies that the 16-dimensional Barnes-Wall lattice has optimal density among all 16-dimensional lattices with Hurwitz structures.
