Description |
Open, discrete Q-mappings in Rn, n > 2, Q 2 L1 loc, are proved to be absolutely continuous on lines, to belong to the Sobolev class W1,1 loc , to be differentiable almost everywhere and to have the N−1-property (converse to the Luzin N-property). It is shown that a family of open, discrete shell-based Q-mappings leaving out a subset of positive capacity is normal, provided that either Q has finite mean oscillation at each point or Q has only logarithmic singularities of order at most n − 1. Under the same assumptions on Q it is proved that an isolated singularity x0 2 D of an open discrete shell-based Q-map f : D \ {x0} ! Rn is removable; moreover, the extended map is open and discrete. On the basis of these results analogues of the well-known Liouville, Sokhotskii-Weierstrass and Picard theorems are obtained. |
