The analogue of the strong Viterbo conjecture for systolically convex domains

Let (TT2,ωcan)(T^*\mathbb T^2,\omega_{\rm can}) be the cotangent bundle of the two-torus, and let S\mathcal S denote the class of systolically convex domains defined in the source. A symplectic capacity is ball-normalized when it is normalized on symplectic balls. The analogue of the strong Viterbo conjecture. All ball-normalized capacities coincide for elements in S\mathcal S. The conjecture is proposed as an analogue of the strong Viterbo conjecture for systolically convex domains in TT2T^*\mathbb T^2. The source establishes coincidence in several subclasses, while also giving an example outside S\mathcal S where two ball-normalized capacities do not coincide; the general claim remains open.
