revised Superfields and the Inconsistency of regularization by dimensional reduction
Previous edit incorrectly modified the meaning of 3rd paragraph and made other wording awkward. Edits for the sake of a BUMP (although I appreciate the sentiment) should not be approved.

comment Vacuum to vacuum transition amplitude using functional integral
Vladimir is correct. Try thinking of $\phi$ and $J$ as vectors with a continuous index $x$ and so $P$ and $P^{-1}$ are matrices indexed by $x$ and $y$. To make this work, the functional version of $P$ is actually $P(x,y) = (\square+m^2-i\epsilon)\delta^4(x,y)$ where $\delta$ is the Dirac delta function.
