On the inverse $K_I$-inequality for one class of mappings

Complex Variables 2022-05-10 v3

Abstract

We study mappings differentiable almost everywhere, possessing the NN-Luzin property, the N1 N^{\,-1}-property on the spheres with respect to the (n1)(n-1)-dimensional Hausdorff measure and such that the image of the set where its Jacobian equals to zero has a zero Lebesgue measure. It is proved that such mappings satisfy the lower bound for the Poletsky-type distortion in their domain of definition.
