The groups of points on abelian varieties over finite fields

Abstract

Let AA be an abelian variety with commutative endomorphism algebra over a finite field kk. The kk-isogeny class of AA is uniquely determined by a Weil polynomial fAf_A without multiple roots. We give a classification of the groups of kk-rational points on varieties from this class in terms of Newton polygons of fA(1t)f_A(1-t).
