Non-crossing geometric spanning trees with bounded degree and monochromatic leaves on bicolored point sets

Mikio Kano, Kenta Noguchi, David Orden

Let $R$ and $B$ be a set of red points and a set of blue points in the plane, respectively, such that $R\cup B$ is in general position, and let $f:R\to \{2,3,4,\dots \}$ be a fu…
