Primitive Central Idempotents Of Rational Group Algebras

Tijdschriftbijdrage - Tijdschriftartikel

We give a description of the primitive central idempotents of the rational group algebra QG of a finite group G. Such a description is already investigated by Jespers, Olteanu and del Río, but some unknown scalars are involved. Our description also gives answers to their questions.
