http://ask.sagemath.org/question/23578/what-is-katsura-ideal-in-documentation/?answer=23580#post-id-23580Three of Katsura's papers have "Ideal structure" or "Ideal structures" in the title.
A quick [search](https://www.google.com/search?q="katsura+ideal") reveals more papers
defining or referring to the notion of a Katsura ideal.
See in particular the paragraph across pages 15 and 16 in the memoir
[Operator Algebras for Multivariable Dynamics](http://books.google.com/books?id=1zK_AwAAQBAJ&pg=PA15&lpg=PA15)
