The Lukic Conjecture

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.

Statement

Let μ\mu be a probability measure on the unit circle with Verblunsky coefficients α\alpha. Lukic conjectured that a weighted entropy condition with finitely many critical points is equivalent to a decomposition of α\alpha into components localized at those points. A counterexample with two critical points of multiplicity three refutes it: the sequence satisfies the decomposition conditions while the corresponding weighted entropy is -\infty.

Context

A named conjecture in OPUC spectral theory (higher-order Szegő theorems).

nobody looking

    The counterexample - two phase modes with common power-decay exponent 3/203/20 - was found by GPT-5.6, as the abstract states directly; the author developed and verified the construction.
