Explicit compactifications of moduli spaces of Campedelli and Burniat surfaces
We describe the compactifications obtained by adding slc surfaces X with
ample K_X, for two connected components in the moduli space of surfaces of
general type: Campedelli surfaces with \pi_1(X)=\bZ_2^3, and Burniat surfaces
with K_X^2=6.Comment: Color version; black-and-white version at

On the existence of ramified abelian covers
Given a normal complete variety , distinct effective Weil divisors
of and positive integers , we spell out the
conditions for the existence of an abelian cover of branched with order
on .
As an application, we prove that a Galois cover of a normal complete toric
variety branched on the torus-invariant divisors is itself a toric variety.Comment: Dedicated to Alberto Conte on his 70th birthday. Version 2: the
assumptions in the application (Thm. 3.7) have been weakened; minor
modifications of the expositio
