We consider arrangements of pseudo-lines in the Euclidean plane where each pseudo-line is represented by a bi-infinite, connected x-monotone curve, s.t. the vertical distance between each pair of such curves is monotonically decreasing (i.e., the pseudo-lines approach each other until they cross, and then move away from each other). We show that such arrangements of approaching pseudo-lines, under some aspects, behave similar to arrangements of lines, while for other aspects, they share the freedom of general pseudo-line arrangements, and are therefore an interesting topic for further research. Joint work with Stefan Felsner and Patrick Schnider.
