BRST & BV symmetry for BF theory with/without ‘cosmological constant’.

It will be introduced BRST and antyfield formalism. The Yang-Mills theory will be used as an illustration. The main part of this presentation consist a BF theory and BF theory with cosmological constant. Despite some BRST transformations are not nilpotent, Batalin–Vilkovisky formalism was used. The BRST complex was found for both cases. Short discussion about taking limit with ‘cosmological constant’ goes to 0 will be added.
