The uniform Lagrangian spectral-width conjecture

About 2 years old · traced to

Let NN be a closed manifold, let gg be a Riemannian metric on NN, and let D1T∗N={(q,p)∣∣p∣g≤1}D_1T^*N=\{(q,p)\mid |p|_g\leq 1\}. Let L(T∗N)\mathfrak L(T^*N) denote the relevant class of closed exact Lagrangians, and let γ(L)\gamma(L) denote the Lagrangian spectral invariant used in the source. Uniform spectral-width conjecture. There exists a constant CN(g)C_N(g) such that, for every Lagrangian L∈L(T∗N)L\in\mathfrak L(T^*N) contained in D1T∗ND_1T^*N,

γ(L)≤CN(g).\gamma(L)\leq C_N(g).

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.
