【 摘 要 】

Comprehensive study of the ageing and the violation of the fluctuation-dissipation theorem in a pure and diluted two-dimensional XY-model were carried out. Two-dimensional XY-model tend to a particular type of phase transition is called a phase transition Berezinskii-Kosterlitz-Thouless associated with the change of the correlation properties of the system.
