摘要：
The topological properties of phase diagrams of liquid crystals with achiral molecules (mesogens) were studied for transitions from the isotropic to uniaxial and biaxial phases by using the phenomenological Landau-de Gennes theory. An isostructural phase transition between two uniaxial nematic phases was investigated. (C) 2002 MAIK "Nauka/Interperiodica".
