  Studying the gauge-invariant renormalizability of four-dimensional Yang-Mills
theory using the background field method and the BV-formalism, we derive a
classical master-equation homogeneous with respect to the antibracket by
introducing antifield partners to the background fields and parameters. The
constructed model can be renormalized by the standard method of introducing
counterterms. This model does not have (exact) multiplicative renormalizability
but it does have this property in the physical sector (quasimultiplicative
renormalizability).
