On a geometric Ramsey number
A partial result: if a planar curve intersects every line in at
most 3 points, then it can be partitioned into 4 convex curves. This result can be
extended to Rd, and the extension implies a good, asymptotically precise, lower bound on a geometric Ramsey number. Joint result with Jiří Matoušek and Attila Pór.
