In the fall 2017 semester Dave Hansen and I organized a seminar on Hida Theory.

Time and place: Thursdays 1:00-2:15 in Mathematics 622.

Here are notes, taken by Pak-Hin Lee.

**References:**

Lecture 1 was based off Chapter 2 of Christopher Skinner's CMI notes, "Galois Representations, Iwasawa Theory, and Special Values of L-functions."

Lecture 2 contains material that can be found, for instance, in Lang's "Cyclotomic Fields I and II." See Chapter 5.

Lectures 4-7 by Pak-Hin Lee used Hida's blue book, "Elementary Theory of L-functions and Eisenstein Series."

He also used the notes of Banerjee-Ghate-Kumar, "\Lambda-adic Forms and the Iwasawa Main Conjecture."

Lecture 8 (the first one on the proof of the main conjecture) used Fitting ideals. A nice reference containing all of the facts I used is Nuccio's notes "Fitting Ideals."
