Let $A/\mathbb{Q}$ be an abelian surface isogenous to a product of elliptic curves that are not $\overline{\mathbb{Q}}$-isogenous and are non-CM. For a subinterval $I\subset[-1,1]$…

Square-root error conjecture. For fixed $t$, $m$, and $I\subset[-1,1]$,

Let $E$ be an elliptic curve without complex multiplication, and let $E(x,t,m,I)$ denote the error in the corresponding Chebotarev–Sato–Tate counting formula, with fixed $t$, $m$,…
