Computation of 2-groups of positive classes of exceptional number fields
Jean-François Jaulent, Sebastian Pauli, Michael Pohst +1
We present an algorithm for computing the 2-group of the positive divisor classes of a number field F in case F has exceptional dyadic places. As an application, we compute the 2-r…
A new Algorithm for the Computation of logarithmic l-Class Groups of Number Fields
Francisco Diaz Y Diaz, Jean-François Jaulent, Sebastian Pauli +2
We present an algorithm for the computation of logarithmic l-class groups of number fields. Our principal motivation is the effective determination of the l-rank of the wild kernel…
Computation of 2-groups of narrow logarithmic divisor classes of number fields
Jean-François Jaulent, Sebastian Pauli, Michael Pohst +1
We present an algorithm for computing the 2-group of narrow logarithmic divisor classes of degree 0 for number fields F. As an application, we compute in some cases the 2-rank of t…
