We prove weak and strong versions of the coarea formula and the chain rule for distributional Jacobian determinants Ju for functions u in fractional Sobolev spaces W s, p (Ω), where Ω is a bounded domain in R n with smooth boundary. The weak forms of the formulae are proved for the range s p> n− 1, s≥ n− 1 n, while the strong versions are proved for the range s p> n, s≥ n n+ 1. We also provide a chain rule for the distributional Jacobian determinant of Hölder functions and point out its relation to two open problems in geometric analysis.
