The Tumbleweed badge means that hardly anyone looked at the question, and nobody expressed any opinion on it. For this very reason, the badge-issuing software cannot give you an explanation of why this happened, since there is no human input to work with.
Let me rate the likelihood of the Tumbleweed reasons you stated:
- too trivial or stupid? Not likely. Math.SE loves trivial and stupid questions.
- misplaced and unintelligible? Very likely. I would state this as mistagged and lacking background information.
- too general? Not likely. If the question is clearly too broad, someone will either say it or vote to close.
- relates to a subject of no interest? Could be. Continuous geometries of von Neumann are not such a hot topic.
- too difficult? By itself this wouldn't be an issue. A focused, clearly stated, interesting question that turns out to be very difficult may end up unanswered but is likely to be upvoted.
Since I think that reason 2 applies to your question, I edited it to include a non-book reference to continuous geometries, and added tags geometric-measure-theory and lattice-order. Will this help? We'll see
I think the concepts are unrelated, but I am not familiar with vN stuff enough to post an answer.
