  We study interplay of electronic correlation, randomness and dimensionality
effects in half-filled random Hubbard chains weakly coupled via an interchain
one-particle hopping. Based on the two-loop renormalization-group approach,
phase diagrams are given in terms of temperature vs. strengths of the
intrachain electron-electron umklapp scattering, the random scattering and the
interchain one-particle hopping.
