%0 Journal Article %T ON WEAKLY INVERTIBLE FUNCTIONS IN THE UNIT BALL %A ROMI SHAMOYAN %A HAIYING LI %J Journal of Mathematical Analysis %D 2010 %I %X We will present an approach to deal with a problem of existenceof (not) weakly invertible functions in various spaces of analytic functions inthe unit ball and polydisk based on estimates for integral operators actingbetween functional classes of dierent dimensions. %K polydisk %K unit ball %K integral operator %K weakly invertible function. %U http://82.114.83.194/ilirias/jma1/repository/docs/JMA1-1-2.pdf
