Lectures on Quantum Field Theory and Functional Integration

Born in 1951, Zbigniew Haba obtained his Ph.D. degree at the University of Wroclaw in 1976, where he then became an assistant professor. Since 1995, he holds a full professorship.He has spent long periods visiting the Department of Physics of Bielefeld University, and also had research stays in the Department of Mathematics, Bochum University,1988, and the Max Planck Institute, Munich. In 1993, he was the Gulbenkian fellow at Lisbon University, and the visiting professor in Freie Universitaet Berlin in 2000.He is the author of a monograph "Feynman integral and random dynamics in quantum physics. A probabilistic approach to quantum dynamics", Kluwer/Springer, 1999.
