The uniform Lagrangian spectral-width conjecture
Let be a closed manifold, let be a Riemannian metric on , and let . Let denote the relevant class of closed exact Lagrangians, and let denote the Lagrangian spectral invariant used in the source. Uniform spectral-width conjecture. There exists a constant such that, for every Lagrangian contained in ,
The claim asks for a uniform bound on the spectral invariant for all such Lagrangians. The supplied text does not identify a resolution or provide an attribution, so its current status should be checked.
