A new pointwise bound for $3$ -torsion of class groups

Stephanie Chan, Peter Koymans

Ellenberg--Venkatesh proved in 2007 that $h_{3} (d) ≪_{ε} ∣ d ∣^{1/3 + ε}$ , where $h_{3} (d)$ denotes the size of the $3$ -torsion of the class group of $Q (d)$ . We improve th…

Serre's problem for multiple conics

Stephanie Chan, Peter Koymans, Nick Rome

We prove the refined Loughran--Smeets conjecture of Loughran--Rome--Sofos for a wide class of varieties arising as products of conic bundles. One interesting feature of our varieti…
