On Small Iwasawa Invariants and Imaginary Quadratic Fields
If p is an odd prime that does not divide the class number of the imaginary quadratic field k , and the cyclotomic Z -extension of k has A-invariant less than or equal to two, we prove that every totally ramified Zextension of k has //-invariant equal to zero and …
