Does contracting a non-crossing edge of a $k$-plane graph change the $k$-planarity?
A graph is $k$-planar if it can be drawn on the plane such that each edge is
crossed at most $k$ times. A graph together with a $k$-planar drawing is a $k$-plane
graph. Hence, by definition, $0$-...

Is there is a constant $c$ such that toroidal graphs are minor-$c$-colorable?
A toroidal graph is a graph that can be embedded on a torus. In other words, the graph's vertices can be placed on a torus such that no edges cross.
A minor of graph G is a graph obtained from G by ...
