For each , partial evaluation of the compact kernel on the two witness tensors defines a compact scalar distribution by
It satisfies
with the fixed volume convention. In particular,
Proof. The witness tensors are smooth, although not compactly supported. Compactness of makes (eq:q-partial) meaningful.
More explicitly, choose smooth compact cutoffs equal to one near the first and second support projections of . Then
This is independent of those cutoffs and continuous in . Equivalently, multiply by the smooth witness coefficients, contract its tensor indices, and push forward to the scalar slot. The pushforward is proper because the kernel is compact.
By Theorem thm:trep and algebraic complexification, the left side of (eq:t-to-j) equals . Theorem thm:Opol(6) identifies this with . Equation (eq:j-pair) proves equality for every real smooth scalar.
For a complex compact test, apply that equality separately to its real and imaginary parts. Complex linearity proves (eq:q-equals-j) as a distributional equality.
