Cohomology and Hodge Theory on Symplectic Manifolds: I

Tseng, Li-Sheng, Yau, Shing-Tung

Understand

We introduce new finite-dimensional cohomologies on symplectic manifolds.

  • Each exhibits Lefschetz decomposition and contains a unique harmonic representative within each class.
  • Associated with each cohomology is a primitive cohomology defined purely on the space of primitive forms.
  • We identify the dual currents of lagrangians and more generally coisotropic submanifolds with elements of a primitive cohomology, which dualizes to a homology on coisotropic chains.
