Our goal in this section is to recall the basic theory about valuations and heights without proofs. Following [3] we will define heights on V.. We will follow the proof in [2],

The theorem of Fouvry and Kl¨ uners on 4-ranks is one of the strongest pieces of evidence for the heuristic of Cohen– Lenstra and Gerth about the distribution of the p-Sylow subgroup

with a Markov process on Eisenstein polynomials, culminates into a mass-formula for unit filtrations. As a bonus the proof leads in many cases to explicit invariants of

Chapter 2 is a joint paper with Efthymios Sofos about statistical properties of ray class groups of fixed integral conductor of imaginary quadratic number fields.. In a refined

Met dit statistische model voor straalklassengroepen verkrijgen onze resultaten over de 4-rangen en Varma’s resultaat over de 3-torsie een precieze heuristische verklaring en worden

Let L/K be a finite Galois extension of fields, with Gal(L/K) being an elementary abelian 2-group and with char(K) = 2. Denote by F2[Gal(L/K)] the group ring of Gal(L/K)
