-rigidity of the Hamiltonian diffeomorphism group of symplectic rational surfaces
Marcelo Atallah, Cheuk Yu Mak, Weiwei Wu
We investigate the -topology of the group of symplectic diffeomorphisms of positive symplectic rational surfaces. For all but a few exceptions, we prove that the group of Hami…
Infinite connected components of the space of symplectic forms on ruled surfaces
Jianfeng Lin, Weiwei Wu
We provide an infinite family of diffeomorphic symplectic forms on ruled surfaces, which are pairwise non-isotopic. This answers a uniqueness question regarding symplectic structur…
Dax invariants, light bulbs, and isotopies of symplectic structures
Jianfeng Lin, Weiwei Wu, Yi Xie +1
This paper addresses several isotopy problems on -manifolds. First, we classify the isotopy classes of embeddings of in that are geometrically dual to $\{\mbox…
Symplectic Torelli groups of rational surfaces
Jun Li, Tian-Jun Li, Weiwei Wu
We call a symplectic rational surface \textit{positive} if . The positivity condition of a rational surface is equivalent to the existence of a divisor $D…
Topology of symplectomorphism groups and ball-swappings
Jun Li, Weiwei Wu
In this survey article, we summarize some recent progress and problems on the symplectomorphism groups, with an emphasis on the connection to the space of ball-packings.
Spherical twists and Lagrangian spherical manifolds
Cheuk Yu Mak, Weiwei Wu
We study Dehn twists along Lagrangian submanifolds that are finite quotients of spheres. We decribe the induced auto-equivalences to the derived Fukaya category and explain its rel…
