Well I'm not a math major, but I have taken linear algebra, which includes formal proofs. But since I have not written a proof in a while and have not taken a modern analysis class, I would appreciate the expertise of someone like yourself. The head of my colege's math department has agreed to help me some with this, but she is pretty busy, and I'd like to figure out as much as I can by myself. There is also a knowledge barrier since she does not understand socionics yet.
I have two end goals for this project. First, I would like people to be able to understand how socionics works on a fundamental level. Second, I would like to apply the structure with statistics, which would help with empirical research and could be developed into a diagnostic test.
My motivation is I see a very simple way to put socionics together as an abelian group which I think almost everyone can grasp. I also think there is a beauty to simplicity.
The dichotomies are abelian and the intertype projections are abelian, but I agree that both together are not. I haven't fully thought about this problem, but it can easily be solved by dividing the rational types from the irrational.
