Boolean algebras/Unknown notation
0
$begingroup$
Does someone know what is meant (in the context of trees and Boolean algebras by Shelah) here on the page 8 right above Remark 1.5:
$${langlerangle}cup{langlexirangleotimes_{zeta(*)}deta:xiin w text{ and }etain I_xi}$$
?
I do not know what $d$ means in this notation, nor can I find it in the text.
All of the relevant notation (except for the questioned $d$) is given on the pages 8 and 9.

It is a Shelah's style complicated paper dealing with Boolean algebras, ordinals and trees. All the definition could be found on the pages 8 and 9, but for $d$. I hope that someone might have an idea what it denotes.

Excellent, how do I contact him? I'm from time to time lost in Shelah's papers and a brief consultation would help me enormously.

I believe this is a typo and that the $deta$ should just be $eta$. That this is a typo is reinforced by (2) in Remark 1.5, and the fact that the notation $deta$ (or $d(text{anything})$ never appears in the rest of the paper. (And the fact that Shelah's papers aren't exactly renowned for their readability and lack of typos).
