Let G be a commutative affine algebraic group over a field F, and let H: Fields F→ AbGrps be a functor. A (homomorphic) H-invariant of G is a natural transformation Tors (−, G)→ H, where Tors (−, G) is the functor Fields F→ AbGrps taking a field extension L/F to the group of isomorphism classes of G L-torsors over Spec (L). The goal of this paper is to compute the group Inv hom 1 (G, H) of H-invariants of G when G is a group of multiplicative type, and H is the functor taking a field extension L/F to L×⊗ Z Q/Z.
