F_q[t]上定二元二次型的表示

Representations of Definite Binary Quadratic Forms over F_q[t]

Jean Bureau, Jorge Morales

摘要:

本文证明了F_q[t]上的二元定二次型,其中q为奇数,可由它所代表的多项式在3 m-2阶下等价地完全确定,其中m为其判别式的阶。当q>13时,刻画了F_q[t]上所有类数为1的定二元形式.

英文摘要:

In this paper, we prove that a binary definite quadratic form over F_q[t], where q is odd, is completely determined up to equivalence by the polynomials it represents up to degree 3m-2, where m is the degree of its discriminant. We also characterize, when q>13, all the definite binary forms over F_q[t] that have class number one.
