A measure and orientation preserving homeomorphism with approximate Jacobian equal $-1$ almost everywhere (1510.05575v2)
Published 19 Oct 2015 in math.CA and math.DS
Abstract: We 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 we prove that our homeomorphism can be uniformly approximated by orientation and measure preserving diffeomorphisms.
