Explicit Hamiltonian Classification in the $F_{4} (0)$ Toric Degeneration of $C P^{2}$

Han Lou, Shuo Zhang

We give an explicit coordinate description of the Hamiltonian isotopy classes of the regular Lagrangian torus fibers of the smoothing $\widehat{F}_4(0)$ of the $F_4(0)$ toric d…

On Lagrangian Tori in $S^{2} \times S^{2}$

Han Lou

In [FOOO12], K. Fukaya, Y. Oh, H. Ohta, and K. Ono (FOOO) obtained the monotone symplectic manifold $S^{2} \times S^{2}$ by resolving the singularity of a toric degeneration of a Hirzeb…

On the Hofer-Zehnder conjecture for semipositive symplectic manifolds

Marcelo S. Atallah, Han Lou

We show that, on a closed semipositive symplectic manifold with semisimple quantum homology, any Hamiltonian diffeomorphism possessing more contractible fixed points, counted homol…

Han Lou, Mingxing Zhang

Let $M$ be a simple 3-manifold, and $F$ be a component of $\partial M$ of genus at least 2. Let $α$ and $β$ be separating slopes on $F$ . Let $M (α)$ (resp. $M (β)$ ) be the manifold o…
