Abstract:
Let ${F \in W_{{\text {loc}}}^{1,n}(\Omega ;{\mathbb {R}^n})}$ be a mapping with nonnegative Jacobian ${{J_F}(x) = \det DF(x) \geq 0}$ for a.e. x in a domain ${\Omega \subset {\mathbb {R}^n}}$. The dilatation of F is defined (almost everywhere in ${\Omega }$) by the formula \[ K(x) = \frac {{|DF(x){|^n}}}{{{J_F}(x)}}.\] Iwaniec and Šverák [IS] have conjectured that if ${p \geq n - 1}$ and ${K \in L_{loc}^p(\Omega )}$ then F must be continuous, discrete and open. Moreover, they have confirmed this conjecture in the two-dimensional case n = 2. In this article, we verify it in the higher-dimensional case ${n \geq 2}$ whenever ${p > n - 1}$.References
