Conjecture 3 of the Dynamical Sampling Survey

Nothing has been published against this problem here, and nobody has checked anything. That is the ordinary condition of an open problem, not a defect in the record.

1 attempt · no person has looked

Statement

Aldroubi, Cabrelli, Krishtal and Molter conjectured that for a bounded normal operator TT and any vector gg, the normalized orbit {Tkg/Tkg:k0}\{T^k g / \|T^k g\| : k \ge 0\} is never a frame. It can be: an explicit construction produces a normalized orbit that is a frame.

Context

A numbered conjecture from the 2026 dynamical sampling survey, recent and specialized but explicitly posed.
