Microsheaf wrapping conjecture for complex Lagrangians

About 1 year old · traced to

Let XX be a holomorphic exact symplectic manifold with compact core, and let μsh⁡C-c(X)\mu\operatorname{sh}_{\mathbb C\text{-}c}(X) be the finite-microstalk part of the triangulated closure of the perverse microsheaf tt-structure. Let LL be a complex Lagrangian submanifold.

Microsheaf wrapping conjecture. There exists an inductive system {Ei}\{\mathcal E_i\} in μsh⁡C-c(X)\mu\operatorname{sh}_{\mathbb C\text{-}c}(X) such that

lim⁡i→+∞Ei≅GPS⁡(L).\lim_{i\rightarrow +\infty}\mathcal E_i\cong \operatorname{GPS}(L).

The source explicitly remarks that this conjecture seems to be false in general and should instead be viewed as a guiding principle; thus the proposed statement is refuted as stated.
