coincide with the Bohmian trajectories. Hence, the Bohmian trajectories should no longer be considered "hidden variables". Now they are no longer more "hidden" than the wave...

Shrinking the madness. Go to the Wikipedia article on the Special Linear Group. This article will lead you to many other articles, e.g., Polar decomposition, SL2(R), Mobius transformation (fractional linear transformation (review Complex Variables), Modular Group (to Braid group), the Exponential Mapping, Casimir Invariants, and so on. Most of these links are circular exactly in the sense of mathematics. What some derive as theorems of a set of axioms, others take as their set of axioms, and...
