Plane Spanning Trees
 à la Ramsey

Does every 2-edge-colored simple drawing of K_n contain a monochromatic plane spanning tree? Unfortunately, I do not know the answer. So instead I will discuss some related problems and partial results. (Joint work with Oswin Aichholzer, 
Johannes Obenaus, Joachim Orthaber, 
Rosna Paul, Daniel Perz, Nadja Seiferth, 
Birgit Vogtenhuber, and Alexandra Weinberger.)
