Authored summary

Construct two domains and prove exact equality of every eigenvalue from some index onward while certifying at least one earlier mismatch, or prove that eventual equality forces equality of the complete Dirichlet spectra. A construction must specify the domains sufficiently to prove smoothness, connectedness, and exact spectral claims; numerical eigenvalue agreement is insufficient.

The author reports this result. The outcome applies to this attempt's recorded scope.

Attempt outcome: open strategy

2Authored explanation

Work against the displayed statement and preserve every hypothesis and quantifier. Construct two domains and prove exact equality of every eigenvalue from some index onward while certifying at least one earlier mismatch, or prove that eventual equality forces equality of the complete Dirichlet spectra. A construction must specify the domains sufficiently to prove smoothness, connectedness, and exact spectral claims; numerical eigenvalue agreement is insufficient. Any computation must retain a replayable witness and a matching exclusion or completeness certificate.
