Diophantine rank stability and non-vanishing of -functions

Marius Fischer, Asbjørn Christian Nordentoft

Let be a modular abelian variety of analytic rank . If is a non-trivial finite abelian group such that all prime factors of are sufficiently…

Central values of additive twists of Maaß forms -functions

Sary Drappeau, Asbjørn Christian Nordentoft

In the present paper we study the central values of additive twists of Maaß forms -series. In the case of the modular group, we show that the additive twists (when averaged ove…

Horizontal -adic -functions

Daniel Kriz, Asbjørn Christian Nordentoft

We define new objects called 'horizontal -adic -functions' associated to -values of twists of elliptic curves over by characters of -power order and conduc…

Joint equidistribution of newforms

Asbjørn Christian Nordentoft, Radu Toma

Let be a compact arithmetic hyperbolic surface associated to a maximal quaternion order, let be a cover associated to an Eichler suborder of prime level , and let $Î…

Sparse Equidistribution of Geometric Invariants of Real Quadratic Fields

Peter Humphries, Asbjørn Christian Nordentoft

Duke, Imamoglu, and Tóth have recently constructed a new geometric invariant, a hyperbolic orbifold, associated to each narrow ideal class of a real quadratic field. Furthermore,…

Non-vanishing of geodesic periods of automorphic forms

Petru Constantinescu, Asbjørn Christian Nordentoft

We prove that one hundred percent of the closed geodesic periods of a Hecke--Maaß cusp form for the modular group are non-vanishing when ordered by length. We present applications…
