An introduction to Quantized Lie Groups and Algebras http://arxiv.org/abs/hep-th/9111043
We give a selfcontained introduction to the theory of quantum groups according to Drinfeld highlighting the formal aspects as well as the applications to the Yang-Baxter equation and representation theory. Introductions to Hopf algebras, Poisson structures and deformation quantization are also provided.
Path Integral Methods and Applications http://arxiv.org/abs/quant-ph/0004090
These lectures are intended as an introduction to the technique of path integrals and their applications in physics. The audience is mainly first-year graduate students, and it is assumed that the reader has a good foundation in quantum mechanics.
