     In symplectic geometry, there is a notion of fibrations ${\displaystyle \pi :P\rightarrow M}$ with a symplectic manifold F as fiber, where the structure group is the group of (exact) Hamiltonian symplectomorphisms of the fiber. These are called symplectic fibrations. If the base manifold ${\displaystyle (M,\omega _{M})}$ is also symplectic, there is a weak coupling construction, originally due to Thurston, of defining a symplectic structure on the total space ${\displaystyle P}$.

6. That moves in the same direction as a system of synchronized waves.
7. (petrology, mineralogy) Of or pertaining to a symplectite; symplectitic.
