Global unit squares and local unit squares

Journal of Number Theory, 2008
Let \(K\) be any Galois extension of \(\mathbb Q\), and \(U_K\) be the unit group of \(K\). For any place \(v\) of \(K\), let \(U_v\) be the group of local units of \(K_v\). Here the authors study the following problem: does there exist an odd prime \(p\) such that the map \(U_K/U_K^2\to \prod_{v\mid p} U_v/U_v^2\) is injective.

Covering Segments with Unit Squares [PDF]

Lecture Notes in Computer Science, 2017
We study several variations of line segment covering problem with axis-parallel unit squares in $I\!\!R^2$. A set $S$ of $n$ line segments is given. The objective is to find the minimum number of axis-parallel unit squares which cover at least one end-point of each segment. The variations depend on the orientation and length of the input segments.
