In classical mechanics, it is not useful at all because all the objects satisfies the classical equations of motions. However in quantum mechanics, this is not necessarily true. fflogs file location

"TīmeklisIt is emphasized that the Faddeev-Popov ghosts c and anti c should be hermitian (i.e., c + = c, anti c + = anti c +) in order for the Lagrangian L and the charges Q sub( b) and Q sub(c) to be hermitian. Only with this unconventional assignment, one can achieve a transparent and consistent formulation of the Yang-Mills theories. " - Lagrangian subspace

Define the symplectic complement of W to be the subspace The symplectic complement satisfies: However, unlike orthogonal complements, W ∩ W need not be 0. We distinguish four cases: • W is symplectic if W ∩ W = {0}. This is true if and only if ω restricts to a nondegenerate form on W. A symplectic subspace with the restricted form is a symplectic vector space in its own right.
