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.6 pages, 3 eps figures, to appear in Molecular Crystals and Liquid CrystalsStrongly Correlated Electronstext
