Add to ORKGLet M be a smooth manifold of dimension 2n, and let g be a Riemannian metric on M. An almost-complex structure (abbreviated acs) J on M is an endomorphism of the tangent bundle TM, or equivalently the cotangent bundle T M, of M such that J2 = 1. Such a tensor induces an orientation on M by taking the 2n-form e1 ^ Je1 ^ ^ en ^ Jen to alway
