[institut] [phys4phys] Group for Gravitation, Particle and Fields seminar, Friday 31 March 2023

[Marija Dimitrijevic Ciric]

Dear colleagues,

You are cordially invited to the seminar of the Group for Gravitation, 
Particles and Fields, which will be held on Friday, 31 March 2023 at 
11:00 at the Faculty of Physics, lecture hall 665.


The talk entitled

Batalin-Vilkovisky formalism and quantization of gauge field theories 
(part 2)

is the second in the series of seminars on Batalin-Vilkovisky formalism 
and its applications and will be given by Voja Radovanovic (Faculty of 
Physics, Belgrade).

Abstract: In these series of lectures we will review the 
Batalin-Vilkovisky (BV) formalism and its applications. This formalism 
is a generalization of the BRST quantization and it is frequently used 
in field theory and quantum mechanics. One of the advantages of the BV 
formalism is that it provides a well defined quantization for theories 
that cannot be quanized by the Faddev-Popov path integral approach. In 
particular, gauge field theories with complicated gauge symmetries 
(reducible and/or with an open algebra) are quantized using the BV 
formalism.

In the second lecture we will discuss some examples of reducible and/or 
open gauge symmetries. Then we will introduce notions of antifields, 
antibracket and BV laplacian, derive their properties and discuss the 
classic and the quantum master equations and their solutions.  Finally, 
we will present few relevant examples: Yang-Mills theory, toplogical 
Yang-Mills theory and the antisymmetric tensor field theory.
