Hamiltonian displacement conjecture for Vianna's tori and real projective planes

Let Ta,b,cCP2T_{a,b,c}\subset\mathbb{C}P^2 be Vianna's torus associated with a Markov triple (a,b,c)(a,b,c), let RP2CP2\mathbb{R}P^2\subset\mathbb{C}P^2 be the real projective plane, and let ϕ\phi range over Hamiltonian diffeomorphisms of CP2\mathbb{C}P^2. A displacement conjecture. There exists a Hamiltonian diffeomorphism ϕ\phi such that

Ta,b,cϕ(RP2)=T_{a,b,c}\cap\phi(\mathbb{R}P^2)=\emptyset

if and only if (a,b,c)=(2,b,c)(a,b,c)=(2,b,c). This extends the known non-intersection examples, including T1,1,2T_{1,1,2} and triples having an element equal to 22, while the Clifford torus intersects every Hamiltonian image of RP2\mathbb{R}P^2.
