The -rank of class groups of

Peter Koymans, Adam Morgan, Harry Smit

Let be a quadratic extension. In this paper we study the -rank of the class group , where varies over squarefree rational integers. We…

L-series and homomorphisms of number fields

Harry Smit

While the zeta function does not determine a number field uniquely, the -series of a well-chosen Dirichlet character does. Moreover, isomorphisms between two number fields are i…

L-series and isogenies of abelian varieties

Harry Smit

Faltings's isogeny theorem states that two abelian varieties are isogenous over a number field precisely when the characteristic polynomials of the reductions at almost all prime i…

L-series and isomorphisms of number fields

Harry Smit

Two number fields with equal Dedekind zeta function are not necessarily isomorphic. However, if the number fields have equal sets of Dirichlet -series then they \emph{are} isomo…

Reconstructing global fields from dynamics in the abelianized Galois group

Gunther Cornelissen, Xin Li, Matilde Marcolli +1

We study a dynamical system induced by the Artin reciprocity map for a global field. We translate the conjugacy of such dynamical systems into various arithmetical properties that…

Reconstructing global fields from Dirichlet L-series

Gunther Cornelissen, Bart de Smit, Xin Li +2

We prove that two global fields are isomorphic if and only if there is an isomorphism of groups of Dirichlet characters that preserves L-series.
