Unknottedness of real Lagrangian tori in $S^2\times S^2$
Published 10 Mar 2020 in math.SG and math.GT | (2003.04528v2)
Abstract: We prove the Hamiltonian unknottedness of real Lagrangian tori in the monotone $S2\times S2$, namely any real Lagrangian torus in $S2\times S2$ is Hamiltonian isotopic to the Clifford torus $\mathbb{T}_{\text{Clif}}$. The proof is based on a neck-stretching argument, Gromov's foliation theorem, and the Cieliebak-Schwingenheuer criterion.
