Abstract
Two abelian varieties over a number field are called strongly iso-Kummerian if the torsion fields and coincide for all . For all we construct geometrically simple, strongly iso-Kummerian -dimensional abelian varieties over number fields that are not geometrically isogenous. We also discuss related examples and put significant constraints on any further iso-Kummerian pair.
