On the elliptic Stark conjecture at primes of multiplicative reduction
(2019-01-01)
Article
Open AccessIn [DLR], Darmon, Lauder, and Rotger formulated a p-adic elliptic Stark conjecture for the twist of an elliptic curve E/Q by the self-dual tensor product ¿ ¿ of two odd and two-dimensional Artin representations. These ... -
CM-points and lattice counting on arithmetic compact Riemann surfaces
(2020-07)
Article
Open AccessLet $X(D,1) =\Gamma(D,1) \backslash \mathbb{H}$ denote the Shimura curve of level $N=1$ arising from an indefinite quaternion algebra of fixed discriminant $D$. We study the discrete average of the error term in the ... -

STEM students’ perception of gender mainstreaming in teaching: the development of a measuring tool
(2019)
Conference lecture
Restricted access - publisher's policyThis study assesses the development process of a tool to measure students’ perceptions of gender mainstreaming in STEM (Science, Technology, Engineering and Mathematics) studies. Within the framework of a pilot project ... -
Beilinson-Flach elements, Stark units and p-adic iterated integrals
(2019-08-14)
Article
Open AccessWe study weight one specializations of the Euler system of Beilinson–Flach elements introduced by Kings, Loeffler and Zerbes, with a view towards a conjecture of Darmon, Lauder and Rotger relating logarithms of units in ... -
On the Galois embedding problem associated to the universal central extension of the alternating group of degree 6
(2013)
Article
Open AccessWe obtain an explicit expression for the obstruction to the solvability of the Galois embedding problem associated to the universal central extension of the alternating group of degree 6. -

Fields of definition of elliptic k-curves and the realizability of all genus 2 sato–tate groups over a number field
(2018-07-01)
Article
Open AccessLet A/Q be an abelian variety of dimension g = 1 that is isogenous over Q to Eg, where E is an elliptic curve. If E does not have complex multiplication (CM), by results of Ribet and Elkies concerning fields of definition ... -
Del Pezzo surfaces over finite fields and their Frobenius traces
(2019-07)
Article
Open AccessLet S be a smooth cubic surface over a finite field q. It is known that #S( q) = 1 + aq + q2 for some a ¿ {-2, -1, 0, 1, 2, 3, 4, 5, 7}. Serre has asked which values of a can arise for a given q. Building on special cases ... -
Hopf Galois structures on symmetric and alternating extensions
(2018)
Article
Open AccessBy using a recent theorem by Koch, Kohl, Truman and Underwood on normality, we determine that some types of Hopf Galois structures do not occur on Galois extensions with Galois group isomorphic to alternating or symmetric ...
