... torus over C and L = X ∗ (T ) then for any abelian topological group W (for example, C× , or R ) there’s a canonical bijection between Π := Hom(Hom(L, W ), C× ) and R := Hom(W, Hom(L̂, C× )) (all homs are continuous group homs). So if W = k × for k a topological field, one sees that Hom(T (k), C× ) ...
