Giovanni Molinari, Michele Schiavina
We study the partition function of Abelian theory with an axial gauge fixing condition given by a Morse--Smale vector field, and we show that it recovers the Milnor metric on…

Homotopies for Lagrangian field theory
Michele Schiavina, Jonas Schnitzer
Consider the variational bicomplex for the space of sections of a graded, affine bundle. Local functionals are defined as an equivalence class of densit…
