We concluded the previous lecture by discussing the finite dimensional version of Wick’s lemma, which computes integrals of polynomials against Gaussian measures as a sum over Feynman diagrams. In today’s lecture, we will see how this procedure carries over to the infinite dimens
These third–year lecture notes are designed for a 1–semester course in topological quantum field theory (TQFT). Assumed background in mathematics and physics are only standard second–year subjects: multivariable calculus, introduction to quantum mechanics and basic electromagneti
Control theory is a vital component of all modern technology because it allows the construction of high performance devices despite large uncertainty in the individual components used to build them. This course provides a basic introduction to modern control theory in a series of
Quantization of the Field This involves two main steps • make basic observables into operators, obeying canonical commutation relations (CCRs) • look for Hilbert space representations for these operators. Strategy: “put the field in a box” = pretend that the space is a torus = im
In these lectures we present a general introduction to topological quantum field theories. These theories are discussed in the framework of the Mathai-Quillen formalism and in the context of twisted N = 2 supersymmetric theories. We discuss in detail the recent developments in Do
Since term is coming to an end soon, and due to some lectures I had to skip, I cannot present all the material in the lecture course I initially had planned. Thus, I collect here briefly some stuff on the quantization of the Dirac field in the canonical formalism, which I have no
