Well, eventually, right here it is-the long-promised "Revenge of the better Rank Symmetric areas and Their basic Domains." while i started paintings on it in 1977, i'd most likely have stopped instantly if somebody had instructed me that ten years may cross ahead of i'd claim it "finished." certain, i'm mentioning it finished-though by no means perfected. there's a great amount of labor happening for the time being because the piles of preprints achieve the ceiling. however, it really is summer season and the sea calls. So i'm really not going to spend one other ten years revising and sharpening. yet, light reader, do ship me your corrections or even your preprints. because of your paintings, there's an Appendix on the finish of this quantity with corrections to quantity I. I acknowledged all of it within the Preface to quantity I. So i'm going to try out to not repeat myself right here. definite, the "recent developments" pointed out in that Preface are nonetheless simply as recent.
