Cyclic abelian varieties over finite fields in ordinary isogeny classes

Algebraic Geometry 2020-01-30 v1

Abstract

Given an abelian variety AA defined over a finite field kk, we say that AA is "cyclic" if its group A(k)A(k) of rational points is cyclic. In this paper we give a bijection between cyclic abelian varieties of an ordinary isogeny class A\mathcal{A} with Weil polynomial fAf_{\mathcal{A}} and some classes of matrices with integer coefficients and having fAf_{\mathcal{A}} as characteristic polynomial.
