Introduction to Tensor Calculus for General Relativity
web.mit.eduspaces is familiar to any student of quantum mechanics who has seen the Dirac bra-ket notation. Recall that the fundamental object in quantum mechanics is the state vector, represented by a ket |ψi in a linear vector space (Hilbert space). A distinct Hilbert space is given by the set of bra vectors hφ|. Bra vectors and ket vectors are linear ...
