Symplectic cohomology with support and aspherical perturbations

Yuhan Sun

For a compact subset of an aspherical symplectic manifold, we show that the symplectic cohomology with support on it remains invariant under suitable perturbations of the symplecti…

A characterization of heaviness in terms of relative symplectic cohomology

Cheuk Yu Mak, Yuhan Sun, Umut Varolgunes

For a compact subset of a closed symplectic manifold , we prove that is heavy if and only if its relative symplectic cohomology over the Novikov field is non-zero.…

Heavy sets and index bounded relative symplectic cohomology

Yuhan Sun

We use relative symplectic cohomology to detect heavy sets, with the help of index bounded contact forms. This establishes a relation between two notions SH-heaviness and heaviness…

Index bounded relative symplectic cohomology

Yuhan Sun

We study the relative symplectic cohomology with the help of an index bounded contact form. For a Liouville domain with an index bounded boundary, we construct a spectral sequence…

Displacement energy of Lagrangian 3-spheres

Yuhan Sun

We estimate the displacement energy of Lagrangian 3-spheres in a symplectic 6-manifold , by estimating the displacement energy of a one-parameter family of Lagrangian tori…

Products and connected sums of spheres as monotone Lagrangian submanifolds

Vardan Oganesyan, Yuhan Sun

We obtain new restrictions on Maslov classes of monotone Lagrangian submanifolds of . We also construct families of new examples of monotone Lagrangian submanifolds,…

-type surface singularity and nondisplaceable Lagrangian tori

Yuhan Sun

We prove the existence of a one-parameter family of nondisplaceable Lagrangian tori near a linear chain of Lagrangian 2-spheres in a symplectic 4-manifold. When the symplectic stru…
