        abstract = {We prove that an open discrete Q-mapping f : D {$\rightarrow$} Rn has a continuous extension to an isolated
boundary point if the function Q x ( ) has finite mean oscillation or logarithmic singularities
of order at most n ? 1 at this point. Moreover, the extended mapping is open and discrete and is
a Q-mapping. As a corollary, we obtain an analog of the well-known Sokhotskii?Weierstrass
theorem on Q-mappings. In particular, we prove that an open discrete Q-mapping takes any
value infinitely many times in the neighborhood of an essential singularity, except, possibly, for
a certain set of capacity zero.}
