Abstract
In this paper we consider the chain rule formula for compositions x {mapping} F(x, u(x)) in the case when u has a Sobolev or BV regularity and F(x, z) is separately Sobolev, or BV, with respect to x and C1 with respect to z. Our results extend to this "nonautonomous" case the results known for compositions x {mapping} F(u(x)).
