- Published 2008

In arrangements of pseudocircles (Jordan curves) the weight of a vertex (intersection point) is the number of pseudocircles that contain the vertex in its interior. We give improved upper bounds on the number of vertices of weight ≤ k in certain arrangements of pseudocircles in the plane. In particular, forbidding certain subarrangements we improve the… CONTINUE READING
