Klein-Gordon Fields in Curved Spacetimes

In General > s.a. causality violation; geometric phase; huygens' principle; Superradiance.
* Dynamics: Possible forms are, with → ^1–n/2 under g → ²g, is

g^ab _ab – (m² + R) = 0 ,   from the Lagrangian    = – |g|^1/2 [g^ab _a b + (m² + R) ²] .

Minimal coupling is = 0; when m = 0, setting = (n–2)/4(n–1) (= 1/6 in 4D) makes the equation conformally invariant.
