My current WIP combines fantasy with economics, and governs them with mathematics. Real world theories and equations are given a fantasy spin, but still have the same level of complexity.

Needless to say, it's going to be dense. My protagonist is a brilliant mathematician who goes up against an even more brilliant society of intellectuals.

I'm trying to present it in two "layers" -- one where less technical people will get the gist of it, and one where more technical people will understand the meaning of it.

Is there a correct term for this "genre"?
Is there a hard science fiction equivalent for fantasy?
What other novels do what I'm wanting to do?
Any thoughts?
