Gauge field theory

Enrollment into the program.
Positive result from qoloqia (or written exam) is necessary to enter the oral exam.

Functional methods (along the path integral, functional quantization of fundamental fields, symmetries in the functional formalism);
Systematics renormalization (ultraviolet divergence,
renormalization of quantum electrodynamics; renormalization in higher order of perturbation theory );
Renormalization group (equation Callan-Symanzika, calculation of
renormalization coefficients, beta and gamma
functions , running of coupling constants,
renormalization of local operators, the evolution of mass parameters); Quantization nnonabelian gauge theories (Fadeev-Popov lagrangian,
Ghosts and unitarnost, BRST symmetry, divergence in one loop approximation in neabelskihgauge theories; asymptotic freedom);
Operator product expansion and effective coupling (renormalization quark mass parameters, QCD renormalization interactions incorporates development in operatorsko sum​​); Anomalies in perturbation theory
(triangular diagrams, chiral anomalies and chiral gauge theory);
Quantization of spontaneously broken gauge theories (choice of gauges, Rxi, equivalence theorem of Goldstone bosons, corrections in the approximation of one loop of the weak gauge theory);
Classical solutions in gauge field theories (vortex, monopol, instanton, violation of fermionic quantum numbers).
