Hecke’s L-functions

This volume contains the notes originally made by Kenkichi Iwasawa in his own handwriting for his lecture course at Princeton University in 1964. These notes give a beautiful and completely detailed account of the adelic approach to Hecke’s L -functions attached to any number field, including the proof of analytic continuation, the functional equation of these L -functions, and the class number formula arising from the Dedekind zeta function for a general number field. This adelic approach was d
