On the removability of isolated singular points for degenerating nonlinear elliptic equations

The well known results on the removable singularity of elliptic equations are generalized to the class of degenerating nonlinear elliptic equations. A sufficient condition for the isolated singular point to be removable has been found. in the absence of degeneration, this condition coincides with already known results. (C) 2009 Elsevier Ltd.
