Reading

Useful references

Books and resources I return to.

I will put references (sometimes with hyperlinks) which are useful in my humble opinion.
T.A.Springer Linear Algebraic Groups

A famous textbook for the theory of linear algebraic groups with preliminaries. It is also useful as a reference for structure theorem of reductive groups (Chapter 9).

I remember that my advisor, Yoichi, recommended this book to me when I asked how to start learning representation theory of reductive groups.

C. Mœglin and J.-L. Waldspurger, Spectral Decomposition and Eisenstein Series: A Paraphrase of the Scriptures (French edition)

A careful account of the foundations of Langlands's spectral decomposition theorem, and excellent preparation for reading Arthur's papers on the trace formula.

After reading Godement–Jacquet, I began reading this book on Yoichi's recommendation to learn the general theory of automorphic forms. I found some parts difficult and emailed Waldspurger with questions. I fondly remember how kindly he replied with detailed explanations written in LaTeX.
