Abstract: 

<br>
The Calabi-Yau property of the PoincarŽe-Birkhoff-Witt deformation of a Koszul 

<br>
Calabi-Yau algebra is characterized. The main result partily generalizes Berger 

<br>
and Taillefer's results on 3-dimensional Calabi-Yau algebras to higher dimensional 

<br>
cases. And some known results are derived as appilications. This is a joint work 

<br>
with Q.-S. Wu.
