Problem 4.3.* Let ΩR\Omega \subset \mathbb{R} be a finite union of intervals and ν\nu a weak tiling measure for Ω\Omega. Must ν\nu be expressible as a convex combination of proper tiling measures?

Statement artifacts, not proofs

These records expose exact Lean propositions and statement-only wrappers. Defining a proposition does not supply a proof of it. A placeholder-bearing target also contains no proof. Elaboration checks syntax and types; it does not certify that a formalization perfectly captures every nuance of the informal problem.
