Of-shell quantum mechanics as factorization algebras on intervals

We present, for the harmonic oscillator and the spin-12 system, an alternative formulation of quantum mechanics that is “off-shell”: it is based on classical off-shell configurations and thus similar to the path integral. The core elements are Batalin–Vilkovisky (BV) algebras and factorization algebras, following a pro...

Universal quadratic field equations via homotopy algebras

We explain how the'bar-cobar'construction for homotopy algebras reformulates the equations of motion of arbitrary gauge theories as gauge-covariant quadratic equations for an extended set of fields. The linear term of the new equations encodes the interactions of the original theory, while the quadratic term is univers...
