报告摘要:Dual lattice is an important concept of Euclidean lattices. We first give the right definition of the concept of the dual lattice of a p-adic lattice from the duality theory of locally compact abelian groups. The concrete constructions of ``basic characters'' of local fields given in Weil's famous book ``Basic Number Theory'' help us to do so. We then prove some important properties of the dual lattice of a p-adic lattice, which can be viewed as p-adic analogues of the famous Minkowski's first, second theorems for Euclidean lattices. We do this simultaneously for local fields Q_p (the field of p-adic numbers) and F_p((T)) (the field of formal power-series of one indeterminate with coefficients in the finite field with p elements).
