On the dynamics characterization of complex projective spaces

Abstract: We show that a closed weakly-monotone symplectic manifold of dimension 2n which has minimal Chern number greater than or equal to n + 1 and admits a Hamiltonian toric pseudo-rotation is necessarily monotone and its quantum homology is isomorphic to that of the complex projective space. As a consequence when n = 2, the manifold is symplectomorphic to CP 2 .

“…In the Hamiltonian setting they are sometimes referred to as pseudo-rotations. Recently, symplectic topological methods have been employed to study the dynamics of pseudo-rotations and its connections with symplectic topological properties of the underlying manifold in all dimensions; see [AS,Ban,Br15b,Br15a,ÇGG19,ÇGG20,GG18a,LRS,Sh19b,Sh19c].…”
