ABELIAN SURFACES ADMITTING AN (l, l)-ENDOMORPHISM
We give a classification of all principally polarized abelian surfaces that admit an (l, l)-isogeny to themselves, and show how to compute all the abelian surfaces that occur. We make the classification explicit in the simplest case l = 2. As part of our classification, we also show how to find all principally polarized abelian surfaces with multiplication by a given imaginary quadratic order.
متن کاملEndomorphism fields of abelian varieties
We give a sharp divisibility bound, in terms of g, for the degree of the field extension required to realize the endomorphisms of an abelian variety of dimension g over an arbitrary number field; this refines a result of Silverberg. This follows from a stronger result giving the same bound for the order of the component group of the Sato–Tate group of the abelian variety, which had been proved ...
متن کاملSingularities of Generalized Richardson Varieties
Richardson varieties play an important role in intersection theory and in the geometric interpretation of the Littlewood-Richardson Rule for flag varieties. We discuss three natural generalizations of Richardson varieties which we call projection varieties, intersection varieties, and rank varieties. In many ways, these varieties are more fundamental than Richardson varieties and are more easil...
متن کاملComputing endomorphism rings of abelian varieties of dimension two
Generalizing a method of Sutherland and the author for elliptic curves [5, 1], we design a subexponential algorithm for computing the endomorphism ring structure of ordinary abelian varieties of dimension two over finite fields. Although its correctness and complexity bound rely on several assumptions, we report on practical computations showing that it performs very well and can easily handle ...
متن کاملModuli of Supersingular Abelian Varieties with Endomorphism Structure
0 Introduction In this paper, we investigate the moduli space S g,L of supersingular abelian varieties X with endomorphism structure θ : O L → End(X) and O L-linear principal polarization, where O L is the ring of integers in an algebraic number field L with involution *. General existence of the coarse moduli scheme of polarized abelian varieties with endomorphism structure is shown by using t...
