Theoretical evidence in support of the extended abelian rank one Stark conjecture for the base field ℚ
Connected abelian complex Lie groups and number fields
In this note we explain a way to associate to any number field some connected complex abelian Lie groups. Further, we study the case of non-totally real cubic number fields, and we see that they are intimately related with the Cousin groups (toroidal groups) of complex dimension and rank .
