## Path Integral and Functional Methods in Quantum Field Theory

Path Integral and Functional Methods in Quantum Field Theory. Instructor: Prof. Urjit A. Yajnik, Department of Physics, IIT Bombay. Path Integral Method is an important formal development in quantum mechanics. The first half of the course is useful for any student of quantum mechanics, providing deeper insights into the theory. The second half of the course discusses path integral method in its functional form applied to space-time fields and brings out connection of quantised fields to elementary particles.
