title: Liquid-liquid phase transitions: analytical approaches.
abstract: We consider liquid-liquid phase transitions as an indication of the local structure of condensed substances and investigate their statistics and thermodynamics. In this area there are two analytical approaches which describe the transitions: the first is purely phenomenological, while the second deals with intermolecular couplings. In the present work, we discuss the features of the above approaches and their applicability to metallic liquids.
