Sixteen points in and the inverse Galois problem for del Pezzo surfaces of degree one
Avinash Kulkarni
A del Pezzo surface of degree one defined over the rationals has 240 exceptional curves. These curves are permuted by the action of the absolute Galois group. We show how a solutio…

An arithmetic invariant theory of curves from
Avinash Kulkarni
Let be a field of characteristic 0, let be a uniquely trigonal genus 4 curve, and let be a simply ramified point of the uniquely trigonal morphism. We constr…

An explicit family of cubic number fields with large -rank of the class group
Avinash Kulkarni
We show how to construct infinite families of explicitly determined cubic number fields whose class group has a subgroup isomorphic to using degree del Pezzo…
