Given an elementary function with algebraic branch cuts, we show how to decide which sheet of the associated Riemann surface we are on at any given point. We do this by establishi...

Tilings of the plane by translation show interesting regularity in the disposition of the tiles: in particular, we point out that in the case of a single tile, the obtained congur...
We discuss possible algorithms for interpolating data given in a set of curves and or points in the plane. We propose a set of basic assumptions to be satis ed by the interpolatio...
The Bentley-Ottmann (BO) algorithm, initially designed to report the intersection points of line-segments in the plane, is the prototypical sweep-line algorithm. This video presen...
A thrackle is a graph drawn in the plane so that its edges are represented by Jordan arcs and any two distinct arcs either meet at exactly one common vertex or cross at exactly on...
