Let $\mathfrak{f}_{c,d}$ denote the free class-$c$ nilpotent Lie rings on $d$ generators defined over $\mathbb{Z}$. For $c,d\in\mathbb{N}$, let…

Let $V\subset\mathbb{P}^N$ be an irreducible projective variety, and let $C(V)$ and, where relevant, $\gamma(V)$ be the constants in the Projective Dimension Growth Conjecture. Uni…

For $k \geq 2$, consider spatial matching with distinct supply and demand distributions that are $\eta$-Lipschitz continuous for some constant $\eta>0$ and have densities bounded b…

Generalized sumset pattern conjecture. There exists an infinite set $B\subset\mathbb N$ such that, for every $i=1,\ldots,k$,

Let $E$ be an elliptic curve over $\mathbb{Q}$ and call a prime $\ell$ surjective for $E$ if the $\ell$-adic Galois representation … is surjective; otherwise, call it nonsurjective…

Let $K$ be a number field, $S$ a set of finite places of $K$, and $g\geq 2$ an integer. Let $\mathcal{F}$ be a one-parameter family of complex abelian varieties $A$ of dimension…

Bogomolov–Tschinkel's uniform common-torsion conjecture. There exists a uniform constant $B$ such that

Let $f$ be a complex polynomial automorphism of Hénon type such that $|\operatorname{Jac}(f)|\ne 1$. For an algebraic curve $C$, write $\deg(C)$ for its degree, and write $\deg(f)$…

Uniform Version. Let $g>0$ and $n>0$. Then there exists a bound $N=N(g,n)>0$ such that $\mathscr{A}(K,g,\ell)=\varnothing$ for any $K\in\mathscr{F}(\mathbb{Q},n)$ and any prime…
