Popis: We discuss a parity breaking in theories of fermions, which are trapped inside four-manifolds with boundaries. Even though these theories are parity-invariant at the classical level, the radiative corrections induce parityviolating boundary terms. The effect is present in both gauge and gravitational sectors.
