Cohen-Lenstra heuristics and vanishing of zeta functions for superelliptic curves over finite fields
Hyun Jong Kim
We prove a Cohen-Lenstra type result commenting on the distribution of class group structures amongst function fields of superelliptic curves over finite fields. We also prove a re…

Computing nonsurjective primes associated to Galois representations of genus curves
Barinder S. Banwait, Armand Brumer, Hyun Jong Kim +4
For a genus curve over whose Jacobian admits only trivial geometric endomorphisms, Serre's open image theorem for abelian surfaces asserts that there are o…

Global degrees of covering maps between modular curves
Hyun Jong Kim, Sun Woo Park
Given a projective smooth curve over any field , we discuss two notions of global degree of a finite morphism of smooth curves satis…
