Conjecture on convergence and continuity of the scattering transform for integrable functions
Let , and let and denote the limiting and windowed scattering transforms, respectively. Let be the path space equipped with the Dirac scattering metric, and let condition
holds for all . Moreover, if , then is continuous in with respect to the Dirac scattering metric.
Numerical experiments indicate that the convergence property may hold for all integrable functions, and the claimed continuity is presented as analogous to continuity of the Fourier transform for integrable functions. The source does not establish these assertions, so their resolution remains open.

Progress summary
The conjecture remains open: neither the proposed convergence nor the proposed continuity has been proved or disproved.
The original paper conjectures that condition holds for every , implying convergence of the windowed scattering transforms to the limiting transform, and that the limiting transform is continuous in the Dirac scattering metric. No retrieved source reports a proof, counterexample, or verification; later related work does not address these exact assertions.
Current status (as of September 2026): The convergence and continuity conjectures remain open, with no verified progress recorded; an unsubstantive community mention of a purported counterexample does not establish one.
