For ,
Every internal row and every vertex term is retained.
If has compact distributional order at most , then
on a fixed compact neighborhood of the translation support.
Every equality of actual internal distributions is respected. In particular, if , then the corresponding and all regularized values are zero.
Proof. Insert into (eq:transpose). The result is
which is the pushforward definition of (eq:origin-evaluation).
Linearity gives
Each row uses all terms of (eq:Lambda).
The tensor pairing requires at most five -derivatives and at most -derivatives. On their combined order is at most . The compact-support cutoffs have fixed derivative bounds. This proves (eq:Omega-order).
The construction begins with the actual , so a zero internal distribution remains zero at every stage.
