# Unfree gauge symmetry in the BV formalism

## TL;DR

This paper extends the Batalin-Vilkovisky (BV) formalism to handle gauge theories with unfree gauge symmetry parameters constrained by differential equations, broadening the applicability of the formalism.

## Contribution

It introduces a novel BV approach tailored for theories with unfree gauge parameters, which were not previously accommodated.

## Key findings

- Successfully formulates BV for unfree gauge symmetries
- Demonstrates the consistency of the extended formalism
- Provides a framework for quantizing constrained gauge theories

## Abstract

The BV formalism is proposed for the theories where the gauge symmetry parameters are unfree, being constrained by differential equations.
