Selmer groups in twist families
I am most well known for my work on the distribution of Selmer groups in twist families and its applications to the CohenLenstraGerth heuristics and to Goldfeld's conjecture. This work was the subject of my dissertation at Harvard. The following two paper sequence is the complete form of this work.
The distribution of \ell^\infty Selmer groups in degree \ell twist families I (2022), submitted.
The distribution of \ell^\infty Selmer groups in degree \ell twist families II (2022), submitted.
These papers subsume the following two papers. The first of these had already subsumed the second.
2^\inftySelmer groups, 2^\inftyclass groups, and Goldfeld's conjecture (2017), unsubmitted.
Governing fields and statistics for 4Selmer groups and 8class groups (2016), unsubmitted.
With Peter Koymans, I've also calculated the distribution of 3Selmer groups in cubic twist families of rational elliptic curves of jinvariant 0.
Sums of rational cubes and the 3Selmer group with Peter Koymans (2024), submitted.
