Yes, structr has its own CMS-oriented graph domain, but is not restrictred to that. structr has in its core a wrapper around Neo4j that provides filesystem-like functionality. The serialization/deserialization part is done by kryonet itself.
If you get Neo4j to run on Android, you could use the structr API (structr-core) to build your own Android app, and then sync (push/pull) subtrees between a server instance and the mobile app. But ... do you need real offline persistence on the mobile device? Or would it be sufficient to store the equation graph on a server and just hold a cached view of it on the mobile device, using f.e. the offline capabilities of HTML5? Just a thought ..
