Toric Degeneration and Nondisplaceable Lagrangian Tori in S2×S2

In this article, using the idea of toric degeneration and the computation of the full potential function of Hirzebruch surface F2, which is not Fano, we produce a continuum of Lagrangian tori in S²×S² which are nondisplaceable by a Hamiltonian isotopy.
