11. Technically this division is realized with the Zwanzig projection operator , the essential tool in the derivation. 12. These other projection operators are used to represent inhomogeneous histories by applying lattice operations to homogeneous histories. 13. Molecular orbitals of Td molecules can be determined using reducible representations, SALCs and projection operator techniques. 14. This desired result is achieved through the use of projection operators and two particular important classes of convex cones. 15. More specifically, it is a discrete and exact version of the Radon transform, thus a projection operator . 16. To diagnose bit flips in any of the three possible qubits, syndrome diagnosis is needed, which includes four projection operators : 17. It turns out that it is possible to obtain a similar result on the basis of a set of only 18 projection operators . 18. The key observation of the HPO formalism is to represent history propositions by projection operators on a " history Hilbert space ". 19. Not all projection operators on H can be written as the sum of tensor products of the form \ hat { \ alpha }. 20. S . K .
