Absolute continuity on paths of spatial open discrete mappings

Absolute continuity on paths of spatial open discrete mappings We prove that open discrete mappings of Sobolev classes $$W_\mathrm{loc}^{1, p},$$ W loc 1 , p , $$p>n-1,$$ p > n - 1 , with locally integrable inner dilatations admit $$ACP_p^{\,-1}$$ A C P p - 1 -property, which means that these mappings are absolutely continuous on almost all preimage paths with respect to p-module. In particular, our results extend the well-known Poletskiĭ lemma for quasiregular mappings. We also establish the upper bounds for p-module of such mappings in terms of integrals depending on the inner dilatations and arbitrary admissible functions. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Analysis and Mathematical Physics Springer Journals

Abstract

We prove that open discrete mappings of Sobolev classes $$W_\mathrm{loc}^{1, p},$$ W loc 1 , p , $$p>n-1,$$ p > n - 1 , with locally integrable inner dilatations admit $$ACP_p^{\,-1}$$ A C P p - 1 -property, which means that these mappings are absolutely continuous on almost all preimage paths with respect to p-module. In particular, our results extend the well-known Poletskiĭ lemma for quasiregular mappings. We also establish the upper bounds for p-module of such mappings in terms of integrals depending on the inner dilatations and arbitrary admissible functions.
