SUMMARY:Renormalized quantum BV operator and observables in gauge theories

DESCRIPTION:In this talk I will give an overview of the BV quantization\, 
 which is a universal framework for constructing models in perturbative QFT
  (including gauge theories and effective quantum gravity). Using the versi
 on of this framework developed by Fredenhagen and myself\, one can constru
 ct local nets of observable algebras satisfying Haag-Kastler axioms\, in t
 he sense of formal power series in h-bar. The crucial role is played by th
 e renormalized quantum BV operator\, which is defined abstractly\, without
  the explicit use of the BRST charge.
