Progress in the theoretical investigations of glass transitions

The glass transition from an undercooled melt to a solid is an important basic question unsolved as yet in condensed matter physics, and involves several developing aspects in thermodynamics and kinetics. Theories of the glass transition are still being developed and updated. Even though several theories including the free volume theory that appeared in the 1950s and the current model\|coupling theory have explained some aspects of the glass transition, a complete successful theory of the glass transition is still lacking. In order to clarify the confusion surrrouding glass transitions, a brief outline is first given of the definition, concept and development of the ralevant theories. Based on the analysis of several dominant theories, the main points in the glass transition are brought out.
