The logarithmic class group package in PARI/GP
Karim Belabas, Jean-François Jaulent · Publications mathématiques de Besançon · 2016
This note presents our implementation in the PARI/GP system of the various arithmetic invariants attached to logarithmic classes and units of number fields. Our algorithms simplify and improve on works of Diaz y Diaz, Pauli, Pohst, Soriano and the second author.
