Symplectic symmetries of a hypothetical exotic $C P^{2}$ : a potential construction or a nonexistence proof

Weimin Chen

This paper is primarily concerned with the existence of a symplectic $4$ -manifold, homeomorphic but not diffeomorphic to $C P^{2}$ , which admits a nontrivial finite order symplectomor…

Symplectic configurations: a homological and computer-aided approach

Weimin Chen

Motivated by and extending the technical results in our earlier work on symplectic Calabi-Yau $4$ -manifolds, a general and systematic approach for studying certain unions of symple…
