Completely anticanonical form of Sp(2)-symmetric Lagrangian quantization

The Sp(2)-symmetric Lagrangian quantization scheme is represented in a completely anticanonical form. Antifields are assigned to all field variables including former “parametric” ones πAa. The antibrackets (F,G)a as well as the operators Δa and Va are extended to include the new anticanonical pairs πAa, ΦA. A new version of the gauge fixing mechanism i the Lagrangian effective action is proposed. The corresponding functional integral is shown to be gauge independent.
