Path integral approach to quantum physics

The text is designed to introduce graduate students to the functional integration method in contemporary physics as painlessly as possible without their being forced to spend too much time solely in getting oriented in the mathematical intricacies of measure theory. In the development of the method, there is a striking interplay between stochastic processes, statistical physics, and quantum mechanics. This aspect, I felt, should be stressed in a text on path integration. As for the prerequisites, the student is assumed to be familiar with quantum mechanics and, on the mathematical side, with probability theory. (orig.)
