On the Davenport–Heilbronn theorems and second order terms
Inventiones mathematicae


We give simple proofs of the Davenport–Heilbronn theorems, which provide the main terms in the asymptotics for the number of cubic fields having bounded discriminant and for the number of 3-torsion elements in the class groups of quadratic fields having ...

The André–Oort conjecture for the moduli space of abelian surfaces
Compositio Mathematica


We provide an unconditional proof of the André–Oort conjecture for the coarse moduli space A2,1 of principally polarized abelian surfaces, following the strategy outlined by Pila–Zannier. ... Let Ag,1 denote the coarse moduli space of principally polarized abelian ...

Brauer-Siegel for arithmetic tori and lower bounds for Galois orbits of special points
Journal of the American Mathematical Society


Shyr derived an analogue of Dirichlet's class number formula for arithmetic tori. We use this formula to derive a Brauer-Siegel formula for tori, relating the discriminant of a torus to the product of its regulator and class number. We apply this formula to derive ...

Ax-Lindemann for \mathcal{A}_g


We prove the Ax-Lindemann theorem for the coarse moduli space Ag of principally polarized abelian varieties of dimension g≥1, and affirm the Andr\'e-Oort conjecture unconditionally for Ag for g≤6...

Tensor rank: Some lower and upper bounds
Computational Complexity (CCC)


The results of Strassen and Raz show that good enough tensor rank lower bounds have implications for algebraic circuit/formula lower bounds. We explore tensor rank lower and upper bounds, focusing on explicit tensors. For odd, we construct field- ...
