SHORTEST DISTANCE IN MODULAR HYPERBOLA AND LEAST QUADRATIC NON‐RESIDUE
Tsz Ho Chan · Mathematika · 2016
In this paper, we study how small a box contains at least two points from a modular hyperbola . There are two such points in a square of side length . Furthermore, it turns out that either there are two such points in a square of side length or the least quadratic non-residue is less than .
