Causal intertwining identities

Retarded and advanced Green distributions › Causal intertwining identities · lines 1060–1070

If $\calBz = j$ , then

Q \calFz = - r^{- 1} K^{†} j .

In particular, invariant sources $K^{†} j = 0$ and zero subsidiary Cauchy data preserve $\calFz = 0$ . This is a free subsidiary-equation statement, not an interacting lapse Ward identity.
