I can not see this part "It turns out that in any such exact sequence where the first and third groups are abelian (but not necessarily the second), the third group acts on the first via lifting + conjugation.", and I stuck there. | |

The paper you linked is pretty advanced and might be hard to get through. If you're just starting out, I would suggest picking up Introduction to Cyclotomic Fields by Lawrence Washington. | |
