Arithmetic local constants for abelian varieties with extra endomorphisms
- Mathematics
- 2016
This work generalizes the theory of arithmetic local constants, introduced by Mazur and Rubin, to better address abelian varieties with a larger endomorphism ring than Z. We then study the growth of…
Class Numbers, Cyclic Simple Groups and Arithmetic
- Mathematics
- 2022
Here we initiate a program to study relationships between finite groups and arithmetic-geometric invariants in a systematic way. To do this we first introduce a notion of optimal module for a finite…
Ranks of abelian varieties in cyclotomic twist families
- Mathematics
- 2021
Let A be an abelian variety over a number field F , and suppose that Z[ζn] embeds in EndF̄ A, for some root of unity ζn of order n = 3 . Assuming that the Galois action on the finite group A[1− ζn]…
Kummer Theories for Algebraic Tori and Normal Basis Problem
- Mathematics

. We discuss the inverse Galois problem with normal basis, concerning Kummertheories for algebraic tori, in the framework of group schemes. The unit group scheme of a group algebra plays an important…
Twists of genus three curves and their Jacobians
- Mathematics

An algebraic curve is a curve defined over by polynomial equations with coefficients in a given field. This thesis treats problems which arise from genus three curves over finite fields. An important…
Finding Large Selmer Rank via an Arithmetic Theory of Local Constants
- Mathematics

We obtain lower bounds for Selmer ranks of elliptic curves over dihedral extensions of number fields. Suppose K/k is a quadratic extension of number fields, E is an elliptic curve defined over k, and…
Selmer ranks of quadratic twists of elliptic curves with partial rational two-torsion
- Mathematics

We study the parity of 2-Selmer ranks in the family of quadratic twists of an arbitrary elliptic curve E over an arbitrary number eld K. We prove that the fraction of twists (of a given elliptic…
ON SELMER RANK PARITY OF TWISTS
- MathematicsJournal of the Australian Mathematical Society
- 2016
In this paper we study the variation of the $p$ -Selmer rank parities of $p$ -twists of a principally polarized Abelian variety over an arbitrary number field $K$ and show, under certain assumptions,…

In w 1 we consider the situation: L/K is a finite separable field extension, A is an abelian variety over L, and A, is the abelian variety over K obtained from A by restriction of scalars. We study…
Isogeny Classes of Abelian Varieties with no Principal Polarizations
- Mathematics
- 2001
We provide a simple method of constructing isogeny classes of abelian varieties over certain fields k such that no variety in the isogeny class has a principal polarization. In particular, given a…
Algebraic Groups and Their Birational Invariants
- Mathematics
- 1998
Since the late 1960s, methods of birational geometry have been used successfully in the theory of linear algebraic groups, especially in arithmetic problems. This book--which can be viewed as a…
Shafarevich-Tate Groups of Nonsquare Order

We give a description of endomorphism rings of Weil restrictions of abelian varieties with respect to finite Galois extensions of fields. The results are applied to study the isogeny decompositions…
A note on the cyclotomic polynomial
- Mathematics

The n -th roots of unity 1, ω, …, ω n - 1 , where ω = exp (2π i \ n ), are linearly dependent in the field Q of rationals since, for instance, their sum vanishes. We are here concerned with the…
