I have a collection of papers and notes that once belonged to Masako IZUMI, former wife of Shin-ichi IZUMI. Most of these are in English but some are in Japanese.
There are hand-written notes for course lectures or drafts of books on real analysis, probability theory, and Fourier series. There are also offprint copies of the IZUMI's journal papers, as well as papers of others on subjects of their interests.
If anyone is interested in obtaining any of these documents, e-mail Tony Martin-Jones at tmj at apex dot net dot au.
