Secant rank and syzygies of projections of elliptic normal curves
Changho Han, Euisung Park
We study the syzygies of projections of elliptic normal curves. Let be an elliptic normal curve of degree , and let denote the projectio…
Counting 5-isogenies of elliptic curves over
Santiago Arango-Piñeros, Changho Han, Oana Padurariu +1
We show that the number of -isogenies of elliptic curves defined over with naive height bounded by is asymptotic to for some e…
Compactifications of moduli spaces of K3 surfaces with a higher-order nonsymplectic automorphism
Valery Alexeev, Anand Deopurkar, Changho Han
We describe Baily-Borel, toroidal, and geometric -- using the KSBA stable pairs -- compactifications of some moduli spaces of K3 surfaces with a nonsymplectic automorphism of order…
Extending the Torelli map to alternative compactifications of the moduli space of curves
Changho Han, Jesse Leo Kass, Matthew Satriano
Determining the limiting behaviour of the Jacobian as the underlying curve degenerates has been the subject of much interest. For nodal singularities, there are beautiful construct…
Enumerating odd-degree hyperelliptic curves and abelian surfaces over
Changho Han, Jun-Yong Park
Given asymptotic counts in number theory, a question of Venkatesh asks what is the topological nature of lower order terms. We consider the arithmetic aspect of the inertia stack o…
