I am a post-doctoral researcher at University of Jyväskylä. My research interest is geometric function theory and analysis on metric spaces.

comment Is this property equivalent to Lusin's property (N) for continuous functions?
Could you please point out which book of Saks you referred to?

Sorry for the confusion, I changed my notation to a more standard one.

comment Is the multiplicity of a Sobolev mapping alwasys locally essentially bounded?
To Fernando Muro:Ifeel like one needs some topological assumption for $f$ to ensure that one can prove such a result. On the other hand, to prove such a result, one needs to use degree theory or other more algebraic topological concept. That is why I add this label.

To ACL: the result you mentioned is the invariance of the domain, which is a simply application of degree theory. Here I am looking for more analytic assumptions on $f$, instead of strong topological assumptions, like you mentioned local injectivity.
