Topological deformations of local gauge theories: a presymplectic BV-AKSZ approach
The same local degrees of freedom can be described by systems with different gauge structure and field content. Standard examples are the duality between the scalar field and the 2-form gauge field in four dimensions, and unimodular gravity, where the cosmological constant becomes a global degree of freedom. In a preci...
