Vanishing Weinstein width conjecture for Vianna's exotic Lagrangian tori

For each Markov triple (a,b,c)M(a,b,c)\in\mathfrak M, let Ta,b,cCP2T_{a,b,c}\subset\mathbb{C}P^2 be Vianna's monotone Lagrangian torus, and let wDW(Ta,b,c;CP2){\frak w}_{\text{DW}}(T_{a,b,c};\mathbb{C}P^2) denote its Weinstein width, defined using Darboux--Weinstein charts and a fixed Riemannian metric. An Weinstein-width conjecture.

inf(a,b,c)MwDW(Ta,b,c;CP2)=0.\inf_{(a,b,c)\in\mathfrak M}{\frak w}_{\text{DW}}(T_{a,b,c};\mathbb{C}P^2)=0.

The conjecture is proposed as a way to examine the conjectural ergodic behavior of the family Ta,b,cT_{a,b,c}; the source establishes only that each individual Weinstein width is positive.
