Abstract

In [FOOO12], K. Fukaya, Y. Oh, H. Ohta, and K. Ono (FOOO) obtained the monotone symplectic manifold S2×S2S^2\times S^2 by resolving the singularity of a toric degeneration of a Hirzebruch surface. They identified a continuum of toric fibers in the resolved toric degeneration that are not Hamiltonian isotopic to the toric fibers of the standard toric structure on S2×S2S^2\times S^2. In this paper, we provide a comprehensive classification: for any toric fiber in FOOO's construction of S2×S2S^2\times S^2, we determine whether it is Hamiltonian isotopic to a toric fiber of the standard toric structure of S2×S2S^2\times S^2.
