Symplectic basis

In linear algebra, a standard symplectic basis is a basis {\mathbf e}_i, {\mathbf f}_i of a symplectic vector space, a vector space with a nondegenerate skew-symmetric form \omega, such that \omega({\mathbf e}_i, {\mathbf e}_j) = 0 = \omega({\mathbf f}_i, {\mathbf f}_j), \omega({\mathbf e}_i, {\mathbf f}_j) = \delta_{ij}. A symplectic basis always exists; in fact, it can be constructed by a procedure similar to the Gram–Schmidt process.[1]
