Description
The study of geometric transversals deals with generalizations of Helly's theorem. Instead of intersecting convex sets by points, we now wish to intersect convex sets by $k$-dimensional affine flats. The modern development of Helly type theorems (colorful, fractional, $(p,q)$ versions) has given rise to a number of new questions about general geometric transversals. In this talk I will survey some recent results and highlight some of the interesting problems in the area. This is based in part on joint work with Otfried Cheong and Xavier Goaoc.
