On subvarieties of singular quotients of bounded domains

Abstract

Let XX be a quotient of a bounded domain in Cn\mathbb C^n. Under suitable assumptions, we prove that every subvariety of XX not included in the branch locus of the quotient map is of log general type in some orbifold sense. This generalizes a recent result by Boucksom and Diverio, which treated the case of compact, \'etale quotients. Finally, in the case where XX is compact, we give a sufficient condition under which there exists a proper analytic subset of XX containing all entire curves and all subvarieties not of general type (meant this time in in the usual sense as opposed to the orbifold sense).
