Balanced lines in two-coloured point sets (2009)
Orden, David, Ramos, Pedro, Salazar, Gelasio
Let $B$ and $R$ be point sets (of {\em blue} and {\em red} points, respectively) in the plane, such that $P:=B\cup R$ is in general position, and $|P|$ is even. A line $\ell$ is {\em balanced} if it...

Orden, David, Ramos, Pedro, Salazar, Gelasio
Let $S$ be a set of $r$ red points and $b=r+2d$ blue points in general position in the plane, with $d\geq 0$. A line $\ell$ determined by them is said to be balanced if in each open half-plane...
