symplectic
EnglishEdit
EtymologyEdit
A calque of complex, coined by Hermann Weyl in his 1939 book The Classical Groups: Their Invariants and Representations. From Ancient Greek συμπλεκτικός (sumplektikós), from συμ (sum) (variant of σύν (sún)), + πλεκτικός (plektikós) (from πλέκω (plékō)); modelled on complex (from Latin complexus (“braided together”), from com- (“together”) + plectere (“to weave, braid”)).
The symplectic group has previously been called the line complex group.

- In symplectic geometry, there is a notion of fibrations 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 is also symplectic, there is a weak coupling construction, originally due to Thurston, of defining a symplectic structure on the total space .
