An extension of Iwasawa's theorem on finitely generated modules over power series rings.
Stark's conjecture in multi-quadratic extensions, revisited
Stark’s conjectures connect special units in number fields with special values of -functions attached to these fields. We consider the fundamental equality of Stark’s refined conjecture for the case of an abelian Galois group, and prove it when this group has exponent . For biquadratic extensions and most others, we prove more, establishing the conjecture in full.
