Perfect Lattices over Imaginary Quadratic Number Fields
Oliver Braun, Renaud Coulangeon
We present an adaptation of Voronoi theory for imaginary quadratic number fields of class number greater than 1. This includes a characterisation of extreme Hermitian forms which i…

Maximal finite subgroups and minimal classes
Renaud Coulangeon, Gabriele Nebe
We apply Voronoi's algorithm to compute representatives of the conjugacy classes of maximal finite subgroups of the unit group of a maximal order in some simple $\QQ $-algebra. Thi…
