• Resumen

  • Let F be a perfect field of characteristic p = 0 and G an Abelian group. For each prime q and each ordinal ? we calculate in terms of G and its sections the Warfield q-invariants of the group V (F G) of all normalized units in the commutative group algebra F G. Surprisingly, these invariants do not depend on F .
