This paper introduces a general perturbative quantization scheme for gauge theories on manifolds with boundary, compatible with cutting and gluing, in the cohomological symplectic (BV-BFV) formalism. Explicit examples, like abelian BF theory and its perturbations, including nontopological ones, are presented. Ver. 2: Improved presentation, especially we added a detailed discussion of the space of states. To appear in Commun. Math. Phys |
