Abstract or Additional Information
I will show how to construct an almost everywhere approximately differentiable, orientation and measure preserving homeomorphism of a unit n-dimensional cube onto itself, whose Jacobian is equal to -1 a.e. Moreover I will prove that the homeomorphism can be uniformly approximated by orientation and measure preserving diffeomorphisms. The talk is based on my joint work with Pawel Goldstein.
