In this lecture notes the author gives a nice introduction to deformation quantization. The quantization problem is discussed in detail (canonical quantization, ordering prescription, etc.) which motivate the notion of different star products. Some interesting examples of deformation quantization are given. Applications beyond quantization theory are found in noncommutative field theories. Starting from a star product algebra, physical applications require to study representation of this algebra. The representation theory is developed from the beginning to the recent development of it including techniques like Rieffel induction and Morita equivalence.
The exposition of the paper is well motivated, well organized and clear.
