Abstract

AbstractIn this note, the geography of minimal surfaces of general type admitting ‐actions is studied. More precisely, it is shown that Gieseker's moduli space contains surfaces admitting a ‐action for every admissible pair such that or . The examples considered allow to prove that the locus of Gorenstein stable surfaces is not closed in the KSBA‐compactification of Gieseker's moduli space for every admissible pair such that .
