Lee Hwa Chung theorem
From Wikipedia, the free encyclopedia
The Lee Hwa Chung theorem is a theorem in symplectic topology.
The statement is as follows. Let M be a symplectic manifold with symplectic form ω. Let α be a differential k-form on M which is invariant for all Hamiltonian vector fields. Then:
-
- If k is odd, α = 0.
-
- If k is even,
, where 
- If k is even,
