Maximally symmetric stable curves II
Michael A. van Opstall, Razvan Veliche
We find a sharp bound for the order of the automorphism group of a stable curve of genus with nodes, and a sharp bound for the order of the automorphism group of such a…
Maximally symmetric stable curves
Michael A. van Opstall, Razvan Veliche
We give a sharp bound on the number of automorphisms of a stable curve of a given genus and describe all curves attaining this bound.
Variation of hyperplane sections
Michael A. van Opstall, Razvan Veliche
A result of Beauville states that with a few positive characterstic exceptions, the smooth hyperplane sections of hypersurfaces of degree in projective space are not all isom…
Genus 2 mapping class groups are not Kahler
Razvan Veliche
The goal of these notes is to prove that the mapping class groups of a closed orientable surface of genus two, with punctures, are not Kähler
