EXPLICIT COMPACTIFICATIONS OF MODULI SPACES OF CAMPEDELLI AND BURNIAT SURFACES
 

Summary: EXPLICIT COMPACTIFICATIONS OF MODULI SPACES
OF CAMPEDELLI AND BURNIAT SURFACES
VALERY ALEXEEV AND RITA PARDINI
Abstract. We describe the compactifications obtained by adding slc surfaces X with ample KX, for two
connected components in the moduli space of surfaces of general type: Campedelli surfaces with 1(X) = Z3
2,
and Burniat surfaces with K2
X = 6.
