We diagonalize exactly the Hamiltonian of the one-dimensional half filled Hubbard model on small clusters of sites with generalized boundary conditions (BCs), and we calculate various correlation functions. We choose the ratio of the onsite repulsion to the hopping matrix element U/t = 1, i.e. an in
