Lehmer without Bogomolov

Fabien Pazuki, Niclas Technau, Martin Widmer

We construct fields of algebraic numbers that have the Lehmer property but not the Bogomolov property. This answers a recent implicit question of Pengo and the first author.

Bertini and Northcott

Fabien Pazuki, Martin Widmer

We prove a new Bertini-type Theorem with explicit control of the genus, degree, height, and the field of definition of the constructed curve. As a consequence we provide a general…

Averages and higher moments for the -torsion in class groups

Christopher Frei, Martin Widmer

We prove upper bounds for the average size of the -torsion of the class group of , as runs through certain natural families of number fields and $\…

Bounds for the -torsion in class groups

Martin Widmer

We prove for each integer an unconditional upper bound for the size of the -torsion subgroup of the class group of , which holds for all but a ze…

Average bounds for the -torsion in class groups of cyclic extensions

Christopher Frei, Martin Widmer

For all positive integers , we prove non-trivial bounds for the -torsion in the class group of , which hold for almost all number fields in certain families of c…

Counting lattice points and o-minimal structures

Fabrizio Barroero, Martin Widmer

Let be a lattice in , and let be a definable family in an o-minimal structure over . We give sharp estimates for the number of lattice points in…
