Abstract
A model glass is studied by classical molecular dynamics and the Voronoicells are determined at various times and temperatures. All their characteristicsof physical interest are studied as a function of temperature. In particular,as temperature increases in the glass phase, the fraction of 4 and 6 edged faces(encircling disclination defect lines) increases at the cost of 5-edged faces. Atthe glass transition this trend is reversed and a majority of pentagons is recoveredin the...Keywords
