Milnor metric for Morse--Smale flows from field theory

Giovanni Molinari, Michele Schiavina

We study the partition function of Abelian $B F$ 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 $E$ the space of sections of a graded, affine bundle. Local functionals $F$ are defined as an equivalence class of densit…

On the local constancy of regularized superdeterminants along special families of differential operators

Michele Schiavina, Thomas Stucker

We consider the flat-regularized determinant of families of operators of the form $D_{I ¨} = [I^´_{I ¨} , d_{\nabla}]$ , where $I ¨ \to I^´_{I ¨} $ are families of degree $- 1$ maps in the twisted de Rha…
