The abstract states that the short-range methods carry over, which lets the authors handle the combination of long-range decay and explicit time dependence without starting over.\n\nThe work does well in staying close to established methods and in flagging the non-scattering component as something worth describing. That keeps the contribution focused and incremental rather than overreaching.\n\nThe soft spot is the absence of visible technical detail on how the estimates change. The abstract gives no function-space assumptions, decay rates, or error bounds, so it is not possible to check whether the time dependence introduces new obstructions or just requires routine adjustments. If the full paper supplies those steps cleanly, the argument holds; otherwise the claim that the methods extend directly remains untested from the outside.\n\nThis is for people already working on scattering for Schrödinger or wave equations with potentials. A reader who knows the short-range literature will see the value in the transfer; others will find it too narrow.\n\nIt deserves a serious referee because the result sits in an active corner of mathematical physics and the central claim is falsifiable once the estimates are on the table.
